Sometimes it is useful, and in some cases necessary, to find out the temperature in the house or country house and, if necessary, control it remotely :

Air temperature inside, in different rooms

Fluid temperature in the heating system (heating boiler)

The air temperature outside, suddenly you are in another city.

What is temperature?

Temperature is information in in electronic format, which must be transmitted over a distance. Of course, this can be done using cellular communications gsm via SMS or via the Internet, there are no other options, because you need to control and manage from anywhere.

Options for performing the temperature control task

1. If the house has a full-fledged Internet with a wi-fi router, then there is no problem, you need to install a thermostat with wi-fi. Through a smartphone mobile application or a PC program, you can receive all the necessary information, control, and, if necessary, manage. In this case, there is no need to pay for additional SIM cards that are inserted into thermostats.

2. Internet is not available everywhere. Therefore, a solution can be found in the use of GSM thermostats and control modules. There are many manufacturers of this equipment.

To know which one to choose, you need to understand the principle of its operation.

How does a gsm thermostat work?

Recently, this device has been placed in a separate group due to its demand in the market. It all started with a regular GSM alarm system - a unit to which you can connect various sensors: motion sensors, fire smoke detectors, gas leak sensors, water leaks, including temperature sensors.

Now, having finalized some software functions for this unit, the relay, equipped with a pair of thermometers, is positioned as a temperature control device, in particular for the boiler.

The operating principle is quite simple:

We set the temperature values ​​(thresholds) on it and get:

Messages about temperature changes below or above a specified threshold in the form of SMS messages.

In this case, the relays connected to the heating gas boiler or freezer are turned on (closed), depending on what is required. A kind of climate control, like in a car. The only difference is that we receive SMS notifications. Although all this can be done manually (close the relay) using SMS commands.

How does a gsm thermostat work?

The average operating principle is as follows:

It is possible to obtain information by sending a request (SMS command), a response is received with the temperature value via SMS

It is possible to receive the status via SMS once a day or automatically according to a schedule. The alert function is pre-programmed, the temperature sensors are set to a certain temperature. The system calls or texts you and informs you, for example, that the temperature at your dacha has dropped below +5 degrees.

Thus, the operating principle of different manufacturers is the same, but the details are different. The main thing is that they suit the requests.

Which gsm module to choose when purchasing?

1. Which performs the functions you need:

Supports required quantity thermometers at the same time (for example 2, 5, 10 ..)

Informs by call or SMS (as convenient for you)

Number of telephones for notification, usually 5, I support all

If needed specifically for a boiler, then compatibility with this boiler model

2. Which manufacturer should I choose? If a company or master makes it for you and gives you a guarantee on the thermostat, then you will trust him.

If you decide to install it yourself, or the master is not sure of the choice, then you can take the most popular selling models, which are produced for at least 5 years.

As a rule, all new products are “raw”, something may not work correctly, there may be malfunctions or something will burn out.

What does it look like? For example like this:

What elements does a gsm thermometer (thermostat) from different manufacturers consist of:

2. Board with parts

There are 2 main parts on the board: the controller (brains) - the atmega32a chip (or similar) and the SIM900 gsm chip, possibly from another manufacturer, which is responsible for communication.

Components of a gsm thermostat board

Their location on the manufacturer's board is 1

Manufacturer location - 2

Thus, if the devices are made from the same parts, then fundamental difference No.

Choose those manufacturers who provide a more convenient guarantee in case of device failure.

This completes the description.

Technical characteristics and composition of the system:

1.GSM module.
2.Digital temperature sensors with a measurement range of -50 - +100 degrees, accuracy 0.5 degrees.
3. Element of informing about a 220 volt power outage at the dacha.

4. It is possible to additionally install an uninterruptible power supply and battery to the system so that the system can operate for a day without electricity.

5.It is possible to connect up to 5 thermometers.

6.The length of the cable from the unit to the thermometer can reach up to 20 meters.

Cable brand KSPV 4x0.5

8. Additionally: it is possible to turn on any electrical load in the house remotely - by telephone, for example, an electric heater.

Most topical issue is a temperature control in the heating system of the house in winter time. Since not everyone has antifreeze liquid in their heating system. It is very often used plain water. And as we know from the laws of physics, at sub-zero temperatures it tends to freeze. But everything would be fine, but during the transition to the ice state, expansion occurs. As a result, the strongest ones are literally torn metal pipes. Therefore, many people think about how to make the heating system warn about a boiler stop or a power outage.

To do this, an electronic thermometer connected to a GSM module with a SIM card is installed at the dacha. This module is an analogue of a mobile phone that transmits information to the owner of the dacha or the plumbers servicing the dacha about an emergency situation - simply a drop in temperature below a given level, for example +20 degrees Celsius in water or +5 degrees in air inside the house.

The photo shows exactly such a device. It consists of a plastic box with a GSM module, a power supply adapter and 2 thermometers. Removing one thermometer 10 cm from the block - it measures the air temperature. The second thermometer is on a 2-3 meter long cable. It can be mounted on a heating pipe. The system does not require any installation. Plugged it in and everything worked. A SIM card is already installed and configured inside.

Security alarm for a summer residence– the choice of prudent people who value the peace and safety of their family. But some people would prefer to be robbed twice rather than have their cottage burn down. And if you were given such a choice, what would you choose? The first option is considered more “humane”, since not all valuables in the house are lost forever. However, we should not forget that both fire and robbery are more than unpleasant things.

Installation of warning devices at the dacha will help protect your home from the disastrous consequences of a fire and from the criminal actions of burglars. You can also find out the temperature at your dacha. Thanks to new technologies that are being actively introduced in the production of various types, there are now many ways to ensure the highest level of safety in the country. Modern sensors for the home can be called “intelligent”, since some of them are connected to communication devices in such a way that in the event of an emergency, an incident signal is transmitted to the control panel of security services, which respond immediately.

Security system installation will provide you with a sense of peace of mind for your property when you are away from the dacha. The price range for the proposed security devices is quite wide, so you can always purchase necessary equipment according to your financial capabilities.
Your safety is only in your hands. And if, due to some circumstances, you cannot afford installation throughout the entire territory of the dacha, take care of at least some of its sections. At a minimum, an alarm system for a dacha should be represented by sensors that are installed on doors and windows. After all, every burglar first tries to enter the house through window or doorways. Some types of dachas emit a loud sound signal, thereby scaring away robbers, others will immediately notify you or the relevant security services

We all know that a harsh winter makes us think about the safety of the heating system in the house, and I will tell you how to do this today.

There are systems to help country property owners to control the temperature in the house. Namely, these systems allow you to find out at any time the temperature in the room where the device with a temperature sensor is installed, as well as set a certain critical temperature at which the device will notify the owner via SMS message or call that the temperature has reached this threshold and it is time to take action .

There are also systems that can themselves control heating equipment, focusing on the same temperature thresholds. Those. The device, receiving information about the temperature from the connected temperature sensor, makes a decision to turn on or off the heating equipment. For example, we set two temperatures in the device: the lower threshold is 10 degrees, and the upper threshold is 20 degrees. It turns out that if the temperature drops below 10 degrees, the corresponding output in the device is activated and the boiler turns on, heating the room begins, after reaching the temperature of 20 degrees, the device understands that it's time to turn off the boiler. Thus, we can set exactly those temperature thresholds that are necessary to maintain the heating system in working condition. These systems also allow significant savings in energy resources.

I think the principle of operation is more than clear and the advantages are obvious. If you want to save money and keep your home heating system working in working order all winter, you just need to install such a simple device.

Let's stop now specifically on devices that perform the function of thermal control, their sufficient quantity and they all differ in their characteristics.

The sensor will let the owners of the house know when the temperature drops below the set threshold, notify about a power outage/on, and also allow you to find out the actual temperature value at any time via SMS. You can even find out the balance of the SIM card installed in the sensor remotely. Therefore, if you need to control only all of the above, then better device simply no, especially since the price for this sensor is still 4800 rub.(especially for government agencies - it does not have a microphone, do not waste government money on test purchases)

• DeviceMega SX-300 light is a compact device with the ability to connect up to 3 temperature sensors simultaneously , allowing you to control temperatures in 3 different locations. For each temperature sensor you can setmine temperature regime and its own algorithm for controlling additional equipment, in total there are 3 outputs for connecting, respectively, 3 control devices. Programmable very flexibly using a computer or SMS commands. Can perform security functions.Price 5290 rub.

• And finally, probably the most functional device for temperature control Mega SX-350 light. We make complex and sophisticated systems using it. In short, connecting to 10 temperature sensors, 6 outputs for actuators, all outputs (i.e. devices connected to them) can be controlled from the phone, all of them can be used in thermal control. It is very flexible to configure, the device’s clear voice menu allows you to avoid getting confused in the controls. In addition, the device provides many security functions for every taste. Price 6350 rub.
  

Well, perhaps all the most popular devices that perform the function of thermal control that our company offers. There are, of course, others on the market, but we will not judge them, since we settled on these for ourselves, because over the years they have shown themselves only on the good side, they are easy to use, install and program, this is shown by the experience of installing hundreds devices for our clients and grateful reviews from the latter.

In this article, I did not dwell in detail on the security functions of the devices, because today the task was to consider the thermal control function, which is the most relevant for our clients at this time. I hope this article will help you decide that a temperature control system is a must to reduce your costs and for your personal peace of mind about your home heating system in general.

In general, I wanted to write a lot and in detail about each system separately, but I think for a better understanding short description would be more appropriate in this article.

And I would like to separately note that each device has its own specific nuances, which you also need to pay attention to when choosing a system, so be sure to contact our specialists for advice.

Initially, be sure to decide what in general you want from the entire system!

Do you have a country house and are you interested in effectively controlling temperature parameters? It turns out that there are currently several more or less effective ways, thanks to which the temperature in the country can be controlled.

The ability to control the temperature in a country house guarantees whole line significant advantages, which we will discuss in this article. And, of course, we will consider the most relevant technologies today that allow us to achieve such results.

For what purpose are remote temperature control systems used?

By installing special equipment through which the temperature for the dacha will be regulated, the following results can be achieved:

• Ensuring comfortable parameters of moisture content in the air (moisture content is the ratio of temperature and humidity in the air in the room).
• Ensuring a longer operational life of a construction project.
  It is no secret that sudden changes in temperature and excess humidity during the cold season are the primary reason for frequent cosmetic and refurbishment. Rapid adjustment of temperature indicators allows you to prevent the appearance of mold on the walls and extend the service life without the need for repair work.
• Ensuring rational use of energy resources and, as a result, saving money.
  In order to ensure optimal parameters moisture content in the air, you can install a gas boiler or electric heater and operate them without interruption throughout the cold season. But, in the end, the bill for consumed electricity or gas will be impressive.
  You can do things differently and use a system in a country house that will turn on the air heating exactly when it is needed. As a result, energy consumption will decrease significantly, which will save a certain amount of money.
• Ensuring the safe operation of a construction site.
  As already mentioned, you can use continuous heating around the clock, even when you are not at home. But, on the one hand, this is not cheap, and on the other hand, it is unsafe, since heating equipment operated in the absence of a person can pose a potential danger.
  The situation is completely different when you remotely receive reliable data on the temperature in the room and, if necessary, can adjust this data up or down.

So now we know what benefits remote temperature control provides. It remains to consider the technologies on the basis of which this control is carried out.

GSM based technologies

Provide effective control Temperature parameters of the air in the room can be determined using a GSM garden thermometer and special temperature sensors. The use of such technology is a relatively new development that is becoming increasingly widespread both in our country and abroad.

Using modern GSM systems, you can not only receive real information about the temperature in the room, but also remotely control these parameters, bringing them to the required value.

The remote control system operates as follows:

• The user of the system, via SMS message via GSM cellular communication channel, receives information about the values ​​of the controlled parameters and, if necessary, sends a control command via message.
• The system, consisting of GSM thermometers and alarm sensors, sets optimal temperature parameters from the user’s point of view and maintains them for the entire specified time.

Remote temperature control is a progressive technology that is actively used in modern Smart Home systems.

Important: A prerequisite for the effective functioning of the GSM thermometer is a stable power supply.
If the power supply is intermittent, you will need to purchase or rent a diesel generator for your dacha.

Currently the following versions of GSM thermometers are available on the market:

• modifications with an integrated thermal converter;
• modifications with external location of the thermal converter.

How does a GSM thermometer work?

• The device is powered by a remote or integrated battery. Thus, the device functions effectively until the battery runs out. After this, the battery automatically begins to charge through the power supply.
• You can configure the device parameters yourself using a PC via a USB connector.
• Depending on the brand and model of the device, it is possible to work with a certain number of phone numbers required to send messages.
• Phone numbers from which sensor configuration is allowed are determined both when configuring using a PC and when configuring from a telephone.
• Depending on the modification and model, the device may have an energy-saving mode, in which the device operates from an internal battery for more than a month.
• The GSM thermometer is supplied to the user with specialized software that simplifies the use of the system.

Features of using remote thermostats

Temperature regulators of this type are installed at a certain distance from heating equipment. The required temperature is set on the thermostat, and the heating device begins to operate in such a mode that the set parameters are constant with minimal deviations.

The photo shows a stylish thermostat that will decorate any room

The thermostat is controlled using keys that duplicate the controls on heating device. The device is equipped with a digital display, which displays readings about the air temperature in the room.

The advantage of this solution is that the price of a remote thermostat is much more affordable than the cost of a GSM thermometer. At the same time, using a thermostat, you can set the operating parameters of heating equipment for several days in advance.

A significant disadvantage of such devices is the inability to notify the user at a distance about malfunctions and malfunctions of heating equipment.

Important: The use of a special thermostat allows you to ensure optimal temperature parameters within a single room or several adjacent rooms.
At the same time, energy consumption becomes more economical, and the life of heating equipment is longer.

Conclusion

If you have any questions or need more useful information, watch the video in this article.

The country house is built - the next step is to monitor and control the electronics in the house from anywhere on the planet. Anyone who has already wondered how to do this knows that inexpensive and simple solutions not on the market. But I carefully studied this issue and found a solution in order to not only receive real-time video broadcast, but also have information about temperature/humidity from wireless sensors installed in different places country house. The sensors also have shock sensors, which allows them to be used as part of a security system. In this case, the connection to the Internet is carried out using an ordinary 3G modem!

So, let's go!

It seems so complicated - I installed a 3G modem in a country house, configured DDNS and it’s done! But no. Mobile operators are very cunning and will not miss an opportunity to make money. The whole problem lies in the “gray” IP address that is issued when connecting to the Internet. I won’t go into technical details, but you will never get remote access from the Internet to a local network in your life. Mobile operators offer the service of a real IP address for 100-150 rubles per month and this is not such a critical amount, but there is one BUT: when using this service, traffic is billed per megabyte at rates of approximately 10 rubles per megabyte! No traffic packages are valid.

There is another option to get remote access: to create a VPN tunnel between the local network in a city apartment and a country house. This will require reflashing the router in the apartment, setting up a VPN server on it, and also purchasing a real IP address service from a city provider. After this, you will be able to remotely connect to your apartment local network, which will be connected to a country house. There are no other solutions.

But if you can’t get remote access to the local network using a 3G modem, you need to look for another solution. Namely: so that the devices that we need to access work through the developer’s public server. That is, devices located behind a 3G modem themselves upload data to a server on the Internet, and we will already connect to this service.

2. A budget option Internet for a country house looks exactly like this. The Asus RT-N10U router costs 800 rubles and supports USB 3G modems out of the box. It has only one antenna, so the maximum speed on the 802.11n network is 150 Mbit. He's like the rest electronic devices connected via a UPS in case of power outages (the energy reserve is sufficient for a day of autonomous operation). Where to get internet? I have no particular desire to advertise MTS, but they are the only ones who offer real unlimited traffic in the Moscow region for only 600 rubles per month. True, they also had to try to deceive them - in the middle of the month they suddenly decided to write off not only 600 rubles monthly, but also 24 rubles per day. As a result, by the time of the next monthly payment there was not enough money in the account to renew and I was left without the Internet. On the good side, the support service admitted their mistake (surprisingly!) and turned on the Internet for the next month for free (in fact, taking into account illegal write-offs - half the price). Internet speed during the day is 3-4 Mbit for receiving and 1-2 Mbit for sending. At night, the reception speed jumps to 7-8 Mbit. The cost of the 3G modem was 100 rubles (700 rubles total cost including the fee for the first month of Internet). No other mobile operator offers unlimited Internet in the Moscow region for this money.

3. Let's start with video surveillance. Let's take a camera from the Chinese manufacturer Harex. This camera is notable for the fact that it works through the Chinese video broadcast service NVSIP. The company produces only wired (Ethernet) cameras; Wifi is not even available as an option. The cost of the camera is 1000 rubles, and the power supply costs another 200 rubles. Setting up the camera is a little non-trivial; for these purposes you need software that exists exclusively for Windows. The camera is already registered with the NVSIP service by default, and you must go into the settings and change the standard password.

4. The NVSIP website itself also works only in Internet Explorer, but this is not important to us because iOS and Android have their own applications. As you might guess, streaming to mobile devices comes at a resolution much lower than 720p, but is quite sufficient for viewing details. Below are real screenshots from the phone screen. There was a small problem with the infrared illumination of the camera - when the camera was installed as in the photograph (this is a temporary solution), the infrared illumination reflected from the white edges of the body and illuminated the entire frame. In reality, IR illumination penetrates 15-20 meters in complete darkness. The camera can be purchased on Aliexpress (http://www.aliexpress.com/store/609704).

The system is easily complemented with other cameras, and archived video is recorded on a computer running the IPClient application. 1200 rubles per camera - great price. Live video can be accessed from anywhere in the world.

5. Let's move on. Remote monitoring and control system - Wireless Sensor Tags (http://wirelesstag.net). These are a variety of wireless sensors powered by a CR2032 battery, which transmit controlled parameters to their own base via a radio channel. In due time, the base connects via Ethernet to a router with the Internet and uploads all the data to the service website. Basic functions include recording temperature, humidity, rotation angle, opening, water leakage, movement, etc. Remote access is possible through a website or mobile device application. The device developers are currently working on creating their own controlled thermostat, as well as integration with the Nest thermostat. This will allow you to remotely turn on/off heating and ventilation.

6. Basic wireless sensor. Measures temperature, humidity and inclination angle. It also has a built-in LED and beeper, which allows you to use it to find lost items. Inside there is a CR2032 battery, which is enough for a year of operation at standard settings for transmitter power (distance up to 60 meters from the base) and data update frequency (every 15 minutes).

7. The leak sensor looks like this. It does not have an LED or beeper. As the manufacturer writes, the sensors themselves are not sealed and are not protected from water; this should be taken into account when placing them. The range also includes motion and opening sensors.

All this was invented in America, the device is unique, there are virtually no alternatives on the market.

8. And here is the main base. Connects to power via USB and via Ethernet to the network. It is registered on the server by its serial number. From interesting observation- communication speed over twisted pair cable is 10 Mbit, but why more? The base has operation indicators: communication with sensors, communication with the server, reception, transmission, error.

9. Kumostat mobile application for iOS. The writing is a little crooked and sometimes glitchy, but it is updated regularly. The main screen shows all the sensors registered on the base (you can take a photo of each directly in the application for easy identification) and the parameters registered by them: temperature, humidity, time since the last update, signal level and security status. If an event occurs, a Push notification is instantly sent to the user’s device (several mobile devices can be registered in the system for one account).

10. Here are some application screens. The first is a list of all events in chronological order. Next are two screens for a specific sensor. The number of customizable parameters is amazing. For example, you can set a controlled temperature range, and if the temperature gets lower or higher, you can set up instant email notifications, push notifications, or even a tweet! And the coolest thing is the graphs of parameter changes for each day. It's incredibly fascinating to watch how the temperature/humidity changes throughout the day.

11. This is what the web interface looks like. The functionality is even greater than that of the mobile application. As you can see, I have 4 sensors: on front door, under the bathroom, in the kitchen and in the well. In the future, I plan to install a controlled thermostat and remotely control the operation of the air source heat pump. Also, the system is simply supplemented with perimeter control sensors and we get a full-fledged burglar alarm(I won’t talk about this for obvious reasons - you’ll figure it out for yourself).

12. Graphs of temperature changes for 6 days. The system apparently stores all data from the moment it is turned on. It’s especially fascinating to watch the temperature change in the well (while the sensor is hanging at a depth of 1 meter from the ground, I plan to hang it deeper).

13. Humidity change graphs simply blow your mind. True, pay attention to the scale of the vertical scale - it turns out that everything is not so scary. In a good way, they need to be calibrated, but I have not yet found a reference hygrometer.

14. The number of settings is amazing. You can even change the operating frequency and data transfer rate between the base and sensors. The service also allows you to use scripts to automate actions and use such interesting things as Geofence - disarming/setting the system when you and your mobile device are within a set radius of an object. Serious vulnerabilities include lack of password encryption account. When you recover your password, it will be sent to you in unencrypted form.

15. How much does it cost? For $25 a universal wireless tag and $65 for a base. Delivery to Russia will also cost $18. Everything in the photo cost $170. Considering that there are no alternatives on the market at all, and trying to make such a device yourself will run into the problem of a “gray” IP address for a 3G modem, I cannot say that it is very expensive.

More detailed information about tags, see the official website -

Quite often a situation arises when it is necessary to organize temperature monitoring. This can be useful for remote objects: greenhouses, warehouses, cellars, etc.

There are many solutions on the market to solve such problems. various solutions from serious industrial to household. We will not consider the first ones, because they are difficult to implement, expensive, and redundant for everyday tasks. Simpler solutions either use outdated and imperfect SMS data transfer technology from a security point of view, or are quite expensive, not convenient, and, most importantly, have paid web services.

Therefore, we created our own own project, thanks to which each of you will be able to organize remote temperature monitoring.

Our solution is budget and consists of two components:

• Design kit for creating a transmitting device
• Free web service for remote temperature monitoring and control

Construction set “LS Monitoring”

The “LS Monitoring” kit is based on the Arduino platform, which makes it easy to learn.

Generally speaking, from a construction set you can make a remote control system for any object, supplementing it with the necessary sensors. For this we have released .

But the teaching example in these lessons is creating a remote temperature control system.

Although the designer pursues educational purposes, a device for transmitting temperature can be assembled from it simply according to the instructions, without going into theoretical details.

You can also connect a heater (such as an electric oven) or a cooler (such as a fan) to the resulting device so that you can not only view the temperature, but also influence it remotely.

It's very simple, because when assembling the constructor you don't need to solder anything! Everything is assembled using special connectors and wires for prototyping.

Web application for remote temperature control “LS Cloud”

The second component of the temperature monitoring system is the web application.

Our LS Cloud app is free and does not need to be used with our construction kit.

If you are able to develop a device for transmitting temperature yourself, you can use the capabilities of “LS Cloud” as a web interface for viewing data. You can read about how to transfer data to our service.

"LS Cloud" has the following capabilities:

Adding an unlimited number of devices

Setting 4 temperature thresholds for alerts

The device can be assigned upper and lower warning and alarm temperature thresholds

Notifying the user via Email and SMS when the temperature crosses specified thresholds and the device crashes

When the temperature leaves the specified limits, the system generates warning and emergency messages and sends them to the user via SMS and Email.

Remote device management

As already mentioned, the device assembled from our construction kit has a relay for connecting any device (for example, a heater or, conversely, a cooler) to maintain the temperature within the required limits.

Through the LS Cloud application, you can remotely turn on or turn off this device.

Displaying temperature on a graph for a selected period of time

LS Cloud provides storage of temperature data over a long period of time. Based on this data, the application builds a graph.

The user can arbitrarily scale the graph and view the temperature for any period of time.

Monitoring the state of communication with a remote device and notifying the user if it is broken

The connection status is displayed as an antenna in front of each device

and in the device data view area on the right side of the screen

In the device settings, you can set a timeout - the time during which the device must be guaranteed to contact the server.

For example, our device “knocks” on the server once every three seconds. We set the timeout to 10 seconds. If during this time the device never communicates, it means something terrible happened to it.

If the signal level is weak, you can increase the timeout time.

If the timeout is exceeded, the system notifies the user that the connection with the device has been lost.

Logging events on the server

The application automatically keeps a log of all events and accidents in the system.

You can view the “LS Cloud” web application at. The password and login to access the test account are indicated on home page applications.

You can order the “LS Monitoring” construction kit.

Remote control of room temperature (remotely) is part of modern system heating and security and fire alarm systems installed in a country house.

GSM modules for temperature control and management

Devices that monitor and regulate temperature conditions (gsm alarms), both at dachas and in office, warehouse, and industrial premises (server rooms, greenhouses, transformer rooms, granaries, freezers etc.), are integrated into common system security, managing access control, video surveillance and remote notification.

Photo: GSM modules temperature control/control

Automatic control of indoor air temperature at a distance is carried out using stationary or wireless temperature sensors. Digital information is sent to the control panel. Depending on the communication capabilities of the remote object, data transfer is carried out via an Internet connection or via SMS - by telephone.

Temperature control devices – GSM alarms

The main task of a temperature alarm device installed in a country house is remote multipoint monitoring of the operation of the boiler and the air temperature in residential premises. The calculation of the quantity, installation and installation of electronic temperature sensors is carried out after examining the heating system at the dacha. The presence of an additional firefighter and security equipment(motion sensors, fire detectors, gas and water leak detectors), connected to the relay inputs of the alarm module.

Photo: Xital GSM expansion units

If the power of the control panel is insufficient, it is necessary to use equipment with a large number of control zones. The Xital GSM company produces expansion units that allow you to additionally obtain 8 control zones for connecting alarm systems, access control systems, CCTV, notifications about the operation of temperature relays of boilers, power surges, and the state of hot water.

In production, GSM systems are used not only for energy-saving heating, but also for controlling ventilation and air conditioning processes, testing transformers and electric motors, temperature conditions in a greenhouse, server room, refrigeration chamber, grain storage, laboratory. Programs for gsm monitoring and control of automation remotely are supplied by the manufacturer and can be easily installed on mobile devices.

GSM SMS alarm - remote temperature control

Technical means and equipment for wireless GSM SMS alarms allow you to organize a remote control, measure and regulate temperature in rooms large sizes. Sitting in a living room chair, through radio-controlled key fobs, buttons and remote controls connected to alarm units and air temperature sensors, the owner can exercise climate control anywhere in the house, regulate the temperature of the water in the pool and the air in the sauna, turn the security system on and off, open entrance lock, etc. At the same time, the integrity of the interior is not violated, original comfort and coziness remains in the heart of your home.

A cozy living room is the heart of the home

For the sake of comfort in your home, you can work hard, choosing exactly those interior items that will make the atmosphere in any room unique and inimitable. Among these products you can find unusual items that will complement the interior of any home, as well as traditional items, such as products for a family living room, cozy bedroom, and even for the kitchen. The main thing is to choose what you like.

Not only the impression of the room, but also the ease of use depends on how correctly you choose the furniture. Its design should be treated with all the attention available to you, because it is the real “face” of your home. This is where those who do not linger at the entrance/hallway level end up, and this is where guests get their first impression of your home.

How much furniture do you need for your living room?

The first thing you should think about when arranging living spaces in your home is how much free space you are willing to allocate for furniture. If you are a supporter of minimalism, then you can limit yourself to:

• table
• sofa
• a pair of armchairs/chairs
• one or two cabinets.

If you are going to use the living room not only as a place for receiving guests, it would be appropriate to install several wardrobes for storing clothes. This is a much more efficient way to use the space in your living room.

Decide on a style

What would you like to see as the coziest place in your home? If your dream is made in high-tech style, choose furniture made of metal and glass. If you are a supporter of the classics, modular or cabinet furniture will suit you.

The cabinet version is found in many houses and apartments. Such furniture is popular because it allows for regular rearrangements, changing the interior. But at the same time, the size of the cabinets remains unchanged.

IN Lately Modular furniture with all its advantages is attracting more and more attention. But before you go to purchase it, decide on a set of elements that you consider necessary for the living room. The contents of wardrobes are increasingly being “moved” into wardrobes, which are installed in the hallway, and sometimes even in the bedroom. You will probably need a stand or cabinet for equipment, as well as a large dinner table. But it won’t fit in a small kitchen, so it is often installed in the living room. After all, this is a gathering place for the whole family! If you're particularly tight on space, a folding option may be a good option.

Quality and quality again

In order for the furniture to serve you for a long time, bringing pleasure from its use, you need to choose quality products from good materials. Here you have three options:

• veneer - from natural wood Only the top linings are made
• Chipboard is a lighter and less expensive material
• solid wood is the most reliable, durable and eco-friendly look materials.

Of course, when purchasing, you will have to focus not only on the advantages and disadvantages of materials, but also on your budget. However, once you make a successful investment, you will provide your home with high-quality and reliable furniture for many years.

When choosing furniture for the living room, think through every detail of your future interior. After all, coziness and comfort are what should “meet” you in own home, Despite everything.

The cost of installing a GSM module in a country house is from 20 rubles. per m

Our online store offers all the necessary equipment and a monitoring program for controlling the operation of a gas boiler, gsm modules, temperature sensors and alarm expansion units, remote temperature control panels.

Until recently, remote control of heating in a dacha was available only to professionals who were able to independently assemble a controller circuit from individual radio components or to those who could pay for such services. However modern manufacturers released many models of controllers for systems " smart House", performing control functions for various equipment, including heating. Another reason why factory control modules are highly recommended is for fire safety.

Requirements for a temperature control and heating control system

Most often, the heating control system in a dacha is faced with the following tasks:

• Firstly, maintaining the minimum required temperature in the house to prevent freezing of the heating system and the building itself;
• Secondly, remotely turning on the heating in the dacha before the arrival of the owners, so that by the time of arrival interior spaces warmed up to a comfortable temperature.

To solve the assigned problems, the heating control system must meet the following criteria:

• Display information about the current indoor and outdoor temperature after user request;
• Send alarm messages if the temperature goes beyond the limit values;
• Remotely control the heating system, with the ability to regulate the temperature in the entire house or in its individual rooms using SMS messages or through special mobile applications;
• Have an affordable cost, high reliability and ease of management;
• Possibility of independent installation and configuration.

The difficulty of developing universal recommendations lies in the fact that very different methods can be used to maintain the temperature in a dacha. The most common ones include: central heating using a gas or electric boiler and radiators, heating with convectors distributed throughout the rooms and traditional stoves or fireplaces.

As a rule, they are used as control devices control panels alarm system GSM alarm, which have advanced functions and an additional interface for controlling various devices.

Control of central heating boilers

For example, we used the GSM alarm controller Block-Post 4, manufactured by EDS LLC.

This device allows you to control the temperature in 8 zones at a distance of up to 100 from the main device. Although the device is intended primarily for an alarm system, its latest firmware has extensive capabilities for working with temperature indicators and the corresponding external periphery:

• Range of perceived measurements -40°С…+120°С with an accuracy of half a degree;
• There is built-in protection against freezing of the coolant; you just need to indicate which channel receives information from the detector and the limit value. If it is exceeded, an SMS warning is sent;
• There is a WEB interface with the ability to maintain statistics and visualize temperature graphs for the period for each temperature sensor;
• You can program the maintenance of a given temperature regime and the prevention of freezing of the heating system.

This device has several advantages compared to others regulating the same functionality. First of all, all modules, including the GSM modem and UPS (up to 12 hours of autonomous operation), are built inside the case, which greatly simplifies its installation and configuration. After the SIM card is installed, the controller automatically connects and registers on the developers’ WEB service, which is located at http://monitoring.gsmbps.ru/. Using standard visualization shell tools, you can easily program the device to perform many functions without knowing any programming language. Connection directly to the boiler is made through relay outputs.

In addition, developers are constantly improving both the hardware of the device and firmware, as well as the software on the server. The only limiting factor to the widespread use of BlokPost controllers is their rather high cost and poor compatibility with devices from other manufacturers.

Convector control - decentralized heating

It is advisable to implement the technical solution using a modular system, since there can be from several to several dozen external controlled devices. As an example, the basic GSM module for building alarm and control systems VM8039D is used. The manufacturer positions this device for security and control of a boiler room or electric heaters residential premises.

The device is configured using a special “Configurator” program supplied in the kit. The program interface is quite clear - object-oriented and does not require specific programming knowledge. There is also a mobile control application for smartphones based on Android, called “Home Logic”, which can be downloaded from GooglePlay.

VM8039D can measure temperature in 32 zones, has a built-in thermostat subroutine and is capable of maintaining the set temperature in the room. To use as a convector control system it is necessary optional equipment same manufacturer:

• VM8069D - expansion unit. Temperature sensors, smoke detectors and relays through which control is carried out are directly connected to it heating system;
• VM8070 - relay for connecting powerful equipment (electric convectors). It is not recommended to exceed a load of 2 kW per device;
• PW1240UPS with NT800 battery - ensures uninterrupted operation of the control system in the event of a power outage.
• MA802 - motion detector for alarm system;
• SN18B20 - outdoor temperature detector - waterproof;
• MP309 - module for measuring values ​​of analog temperature sensors type LM335;
• LM335 - analog temperature sensors, range of measured values ​​-40°C...+100°C, measurement accuracy up to 1°C (quite effective devices at a budget price - up to 1 dollar).
• NM18B20 thermal detectors, set of two pieces.

ATTENTION! VM8069D module has one important feature operation, if you start it without an attached antenna, the device is guaranteed to fail, and there will be no additional device There is no provision for blocking the operation of the device in the absence of an antenna.

The use of universal controllers is justified if, in addition to controlling the heating system, they will also perform other functions: security and fire alarms, control of the irrigation system in the country, remote activation of lighting to create the effect of presence, etc.

How to remotely measure the temperature in a dacha and control heating with special devices

Manufacturers produce a variety of GSM devices, the main specialization of which is remote control of heating devices. The user can choose among many different models:

1. Gsm-climate zont-h1 is a thermostat for indoor installation with an integrated SIM card. The device is compatible with almost all models of gas boilers that have an input for external control. Control can be carried out from a smartphone, PC, tablet with any operating system. On the manufacturer's website https://zont-online.ru/demo you can download free management applications. Changes to basic settings can be password protected. Up to 10 thermal detectors can be connected to the device to determine the temperature inside and outside the building. Setting up the device is quite simple; after installing a SIM card in the slot, an SMS is sent from the user’s phone, and subsequently this number receives administrator rights.
2. Sapsan PRO 5T - the device is a thermostat with 1 temperature detector to which one external electrical device can be connected. The device independently maintains the set temperature range. When the established limits are exceeded, an SMS message is sent to the user. It is possible to configure via a computer. The management utility is included in the kit.
3. Signal XQ is a device other than a GSM module and temperature sensor has a built-in battery inside the case, providing autonomous operation devices within 24 hours from the moment of power outage. Signal XQ sends an alarm SMS in the event of a house blackout, which is no less important than maintaining the temperature, since most modern heating devices volatile. Through the device, you can also organize control of a gas or electric boiler with an external control module.
4. GSM thermometer “Telemetrics” is a device from a domestic company. It is extremely simple to install and use. Can control two electrical devices by applying voltage to the corresponding relay outputs. Management is implemented through free applications on Android and iOS.

A budget option

There is a very economical way to solve the problem. It consists of using GSM sockets. In this case, control is carried out manually through command SMS messages. Examples include the following models:

1. To control one GSM-Socket T4 device from the Telemetrics company. Remotely controls the boiler through control of the power output. You can set the operating temperature range, time frames (weekly schedule and timer up to 24 hours) or control via SMS messages and mobile applications
2. To control several devices, it is recommended to use models of the B-DIN-BOX type - GSM controller for 5 machines. IN this device control of each channel separately, as well as general commands for all lines, is implemented. It is also possible to set a password for each channel.

IMPORTANT! When choosing a specific GSM socket model, pay attention to electrical safety: the quality of the housing, the reliability of the contacts, the presence of grounding, etc. remember, that we're talking about about devices with increased fire hazard.
