GSM automation for comfort

How often do you forget to turn off electrical appliances? Or maybe on the contrary, they wanted to turn them on even before you get home? But in order to turn off the iron that was forgotten at home, you have to return home. Is there any other way to get out of this situation?

To this day in high technology, in apartments you can meet traffic jams, which are almost older than the apartment itself. Automation comes to our homes with some great difficulty. Everything works and thank God. Probably, this is the slogan that the vast majority of residents use. But there are people who bring comfort to their life, drop by drop, but they do it. I belong to such people. I don’t know why, but everything is interesting. Most often, I see the benefits of acquisitions after I acquired a new appliance.

So today we’ll talk about GSM. More precisely, not even about himself, but about how we can manage something with his help. If you do not go into such a serious topic as a smart home and go the easier way, then on the market we can find a number of devices that can somehow control the devices in our house. I love modular equipment for DIN. I love it because DIN is the international standard for installation products in switchboards. All of them have the same dimensions and their installation is as simple as assembling a lego constructor.

Why do you need GSM control

You can easily figure out how to use the device to control devices from the phone. Its main task, as the name implies, is load management. This is turning them on or off. In other words, it’s just a switch, but we can control it from a cell phone. With the help of this device we can control absolutely any loads in the on and off mode.

For example, in the country. We have an introductory shield that distributes electricity throughout the cottage. In a hurry home, you can forget to turn off the opening automatic machine, and accordingly, the switched on devices, such as a fireplace, will continue to work. Having already arrived at home, you recall this, and 100 km to the cottage. Going on and off? Of course, otherwise the cottage can very quickly turn into a pile of ash. And you can set the load control using the phone and turn off everything using the phone.

You can do the same in the apartment. The main thing is to split the wiring in advance so that the refrigerator and other important appliances do not turn off. Which is up to you to decide. Although almost every GSM relay can control several groups of loads and, accordingly, several commands, we can enable and disable various groups. The electrical panel can be arranged to disconnect the entire load EXCEPT and ABSOLUTELY the entire load. This is easy enough to do.

Most of these devices are equipped with an input for a temperature sensor, so we can remotely control heating devices in the room. Thus, heating will not work constantly, but only when we need it. So we can also save electricity with it.

At the same cottage, we can remotely turn on a warm floor or fireplace in advance in order to arrive in an already warm room, and since the device is equipped with its own sensor, it will send you an SMS in advance when the temperature reaches the desired one.

Also, using the GSM module, you can remotely control watering, pumps and lighting. The applications are infinitely many. After all, the main thing that these devices can do is to manage the load. And we need exactly this - comfortably and remotely turn on or off certain electrical appliances. We want to do this for various reasons. Someone because of forgetfulness, someone wants to include something in advance.

For those who forget to turn off the lights and iron, as well as for those who want to come to a warm cottage in advance, even in winter. Who can’t come to water their favorite flowers three times a week and doesn’t want them to dry. Automation has been gaining momentum in our life for a long time, you see, it’s very convenient. And how much joy people experience when they begin to manage such seemingly complex technologies with their own hands.

The GEOMAX company offers to buy a temperature sensor with a GSM module. This device is designed to control the temperature at the protected facility. It is widely used in residential and warehouse premises, greenhouses, incubators, cellars, garages, etc. Such sensors allow you to monitor the situation near heating and heating equipment. They are also an important component of smart home systems.

Our range includes GSM temperature sensors, which have high sensitivity and reliability. You can buy them at the best prices and with the possibility of delivery in Moscow and Moscow region by our own courier service. For the convenience of customers, we offer several payment options and provide professional assistance in choosing the right equipment.

Features of GSM temperature sensors

The device provides continuous measurement of temperature in the controlled area and its continuous comparison with a threshold value that is recorded in the product’s memory. Upon reaching the limit value, the sensor gives an alarm signal using SMS messages or dialing to the phone numbers of the owners. This allows you to protect property from fire and other unforeseen situations.

GSM temperature sensors have the following advantages:

• the ability to remotely control using special service SMS commands. With their help, you can get information about the temperature regime, turn off electrical appliances, etc .;
• wide range of operating temperatures and stability of indications;
• the ability to integrate into a comprehensive security system. This allows you to automatically call the fire department when the permissible temperature is exceeded, maintain the temperature at a given level, turning the heating on and off;
• the ability to work both offline due to the built-in battery, and from an external power source;
• all the necessary software for the operation of the GSM temperature sensor is already installed in the flash memory of the device;
• universality of application on various objects.

What is the limit of modern automation? This article will highlight the issue of remotely controlling a home electrical network using a GSM / GPRS signal. Turn on landscape lighting at the dacha by sending an SMS, or have a complete interactive diagram of the entire power system at home - perhaps thanks to new technologies.

The remote power management system can be used both in country houses and in apartments with the aim of remotely turning on the heating, lighting control  creating the effect of presence at the time of departure, and so on. It is possible to establish management in any power supply network, including the existing one. The technology is based on the work of logical controllers that receive commands on one of the GSM / CSD / GPRS communication channels and execute either them or the corresponding command scripts.

Hardware Overview

The first step to remote power management is to purchase the right equipment. A full-fledged power management system consists of five components, for each of the items a sample will be selected for drawing up the assembly diagram:

Controller Aries PLC 100

Remote control systems also use many peripheral devices:

1. UPSs remain operational when the power is turned off.
2. Relay automation blocks make command execution safe.
3. Software script hosts expand the capabilities of the controller.
4. Modules wireless connection  allow unlimited expansion of the system.
5. User graphical interfaces make it possible to configure equipment without connecting to a PC.

Typical wiring diagrams and turnkey solutions

It is almost impossible to list all the likely uses of GSM controllers in the household. Modern SCADA systems are so diverse that they can solve any problems of a domestic nature without exception. Standard systems, such as XITAL GSM or ESIM120, perfectly cope with common tasks such as lighting or heating control. With them, everything is simple: the controller is installed at the actuator and controls the power through the relay output.

Cons: you have to equip each node with a separate control module, and this is a confusion with mobile numbers, limited capabilities and the lack of a single control center.

There are more advanced options for schemes, but they will have to be assembled on their own. Let's consider only some typical options.

The controller performs the task of greenhouse and garden irrigation, is connected to a common control system, and through it is also controlled remotely. It is possible to execute both commands and program scripts. Relay interlock will prevent accident at user error.

A powerful controller with free programming and several I / O modulators control all systems in the house, including burglar and alarm systems. This is one of the most advanced schemes that can be successfully integrated into the system. smart House.

Sometimes a single device is enough, which is both a modem, and a controller, and an I / O module. The control circuit based on the communicator ES-ForthLogic.

SMS exchange, Android application or remote desktop

It is better to decide in advance how advanced the user interface of the remote control system will be. If we are only talking about heating, a simple SMS exchange will be enough, during which the boiler is given the command codes to which it responds either with a report or by turning on the actuator. Command codes can be predefined on the device, although most devices can change the default values.

More advanced interfaces use data exchange via a GPRS server. The user can use any of the available control channels. For example, while away from home, he can control the controller through the Windows utility, monitor the status of the system through the Android application, while using the CSD dialing number to open the gate.

As for the software of the devices themselves, they do not lend themselves to strict classification and critical evaluation. The fact is that each manufacturer uses its own development environment. Naturally, each device is equipped with a detailed guide to programming, tuning and parameterization, but it can be quite difficult to understand. The situation is aggravated by partial incompatibility of equipment from different manufacturers with standard presets of program memory. Of course, no one bothers to try their hand at logical programming, and in case of failure, turn to an experienced specialist.

From theory to practice - an example of the construction of a simple but functional scheme

The ES-ForthLogic communicator was mentioned above, as well as a list of devices, including a modem, controller and I / O module. Consider them as an example of assembly and make sure that the capabilities of individual solutions are superior to typical automation solutions.

The assembly is carried out in a modular box for 36 seats: first, power wiring and switching equipment are mounted, then telemetry devices and low-current conductors are installed. Assembly wiring diagram:

This assembly allows you to remotely activate any of the operating modes of the pumping station in the pool, heat water, fill the heating system with coolant and warm up the room, turn on lawn watering or separate drip irrigation sections, light the yard and plot, activate the walking or feeding procedure for dogs. The beauty of the assembly is that it is quite simple and interesting to program using the manual, because all the elements are fully compatible.
