Alarm with gsm module to control the car through a smartphone. GSM module installation The simplest gsm module

The GSM-module allows you to remotely control any automation, receiving a signal from a telephone operating in the GSM range, and turning on / off the connected equipment. It is used to open swing and sliding gates, a barrier in parking lots, parking lots, in summer cottages and garage cooperatives, private houses, remote control engineering systems watering, lighting, heating, rebooting servers and routers.

This is how the owner opens the gate at the entrance to the territory

The GSM-module is most widely used as a reliable and low-cost controller for managing group access to an object, compatible with the popular automation of gates and barriers Doorhan and Came.

How the module works

In essence, a GSM module is a radio receiver with an installed sim card of any mobile operator and a controller for processing incoming and outgoing information. The module database contains the phone numbers of all users who have the right to access the closed area. Modern models support recording and storage of up to 2000 numbers, more expensive modifications are capable of processing up to 10,000 numbers.

The principle of operation of the device is shown in the figure.

Schematic diagram of the device

When making a call, the controller checks the incoming number with the recorded data, and if it is in the memory, a command is given to open and actuate the barrier and sliding gate drive. If the number is not in the list, then the device simply hangs up the call without doing anything else. Similarly, the controller opens swing gates equipped with an electric lock and a Doorhan or Came drive.

There is no connection with the caller, or it is disconnected after a few seconds, due to which the cost of paying for cellular services is zero. If the data does not match, then the pass through the enclosing device is not provided. In some models, it is possible to disable identification, and the pass is carried out with any incoming call to the controller. The GSM module control unit is configured using SMS commands, a web interface, a program on a computer connected via a USB port, and an android application for smartphones.

Let's give an example of a gsm-module from Tor-House LLC. There are two models that differ in the number of user numbers and the set of functions. Photo modules in the figure below.

The technical characteristics of the modules are given in the table.

Pros and cons of gsm modules

  • there is no need to purchase individual remote controls, key fobs or cards, and not all barrier control systems are “rubber” and are designed for a limited number of them;
  • you can open a barrier or gate from any place included in the coverage network of a mobile operator, thanks to which it is not a problem to provide a pass for a friend to the territory, being out of reach - not a problem, + simplifying the work of the security service;
  • control - through software or SMS commands, it is possible to add and remove numbers from the database, configure such parameters as admission by day of the week, time of day, entry ban in case of non-payment of mandatory fees, entry log, etc.;
  • the ability to install on automatic barriers and gates of any manufacturer;
  • savings - the price of one gsm controller is approximately equal to the cost of three Came remotes, and with in large numbers users, such automation of travel is significantly more profitable.

And a small fly in the ointment in a barrel of honey - it will be impossible to open a gate or a barrier with a dead phone battery or a zero balance, whether they are Doorhan or Came three times, but the same thing can happen if you, for example, have forgotten or lost the remote control.

  • automatic gates, barriers;
  • boilers;
  • office doors (if there is an electric lock);
  • alarms;
  • cars;
  • and other devices.

We are already familiar with devices such as GSM / MMS cameras (), GSM alarms () that send messages when a motion sensor is activated. These were the first devices using GSM-modules and their use began to expand.

GSM-modules are being actively implemented, they showed the greatest efficiency for control at the entrances to cottage settlements, large residential complexes, commercial facilities with a large number of staff or customers.

Let's say there are 5 houses in the residential complex "Berezka", 500 apartments are multiplied by 1500 rubles. (average key price). The HOA will have to collect 750,000 rubles from the residents. only for the purchase of keys.

It turns out a big economic benefit in comparison with the purchase of keys!

It will be easier to persuade homeowners to buy an automatic barrier when the amount of investment in equipment and installation is 2000-3000 rubles per apartment.

Compared to RFID tags, which can also be used as gate openers, RFID identification is somewhat different, the equipment kit is more expensive, but the range of application is wider.

In the next article, we will analyze the module from SmartAirkey - keyless access to the entrances and parking lots of apartment buildings.

GSM/GPS modules for car alarms promptly inform the owner of the vehicle about its unauthorized use, start, stop or blocking of the power unit, as well as remote performance of service functions. The devices are universal, they can be installed on all brands of cars. Some systems are powered from the on-board network or others from the built-in power supply.

Informing the driver can be carried out by sending SMS or voice messages to pre-specified phone numbers of different mobile operators. Alarm control is performed remotely by means of telephones using a radio channel of a cellular network. Only when commands are given from specific phone numbers will they be accepted.

Status diagnostics can be carried out thanks to the signal of the LED lamp. Advanced car alarms are designed to work autonomously. To connect them, it is enough to connect the devices to the on-board electrical network.

Some Models GSM/GPS modules for car alarms have energy-saving modes to increase the lifespan. So, for example, in standby mode, the integrated battery will consume electricity only if a SIM card is present. And in the event of a power outage, the system will be able to function for several days.

Thanks to the use of GSM / GPS modules, it is possible to create effective security and telematic systems, which are usually connected via the CAN bus. Unlike conventional car alarms, devices of this type give a signal to the owner, regardless of the distance to him. The main thing is to have GSM coverage.

Main functions

Most GSM / GPS modules for car alarms perform the following functions:

    • Connection via 2CAN bus
    • Ability to operate in Slave mode
    • Remote control of engine preheaters
    • Controlling the standard car alarm with your phone
    • Immobilizer bypass module control
    • Possibility of automatic and remote start of the motor
    • Obtaining data on the coordinates of the location of the car

Modern systems allow you to determine the location of the vehicle with an accuracy of several meters. This is the purpose of the GPS receiver. After sending the request, the phone device receives a text message with the coordinates of the location of the vehicle. Even in the event of theft, the owner of the car will be able to quickly find it or find out where a member of his family or another driver who is driving the car is now.

Modern modules can process over fifty commands, they can also be programmed. Several phone numbers can be stored in the SIM card memory, messages will be sent to them. Thanks to the module, you can find out why the alarm went off. Whether the cause was an open door, starting the engine, triggering a shock sensor, disabling the parking brake, etc.

Branded GSM/GPS modules will greatly increase the protection of the car and the convenience of its operation. Thanks to them, vehicle owners will always know where their four-wheeled friend is and what condition its main systems are in.

We will tell you how cheaply you can increase the security of your car using an alarm system with the PIR ALARM GSM module.

The car alarm system with a GSM module allows you to instantly receive information about an attempted hacking and theft of a car anywhere in the world where mobile communications are available. This type of car alarm is of interest to many Russian motorists. A new module is not cheap. For such alarm models, prices start at 12,000 rubles. However, it is possible to upgrade a conventional car alarm with a GSM module. In this article, we will talk about this improvement.

It's no secret that most car alarms with key fobs from major manufacturers in the world can be retrofitted with various functions. So on a standard car alarm, you can install a GSM or GPS module for monitoring and control via a mobile phone. This is used by many manufacturers of car alarms, overestimating the cost of a separate GSM module. Nevertheless, there is a way out. For many models of car alarms, standalone may be suitable GSM module Chinese production. For example, in many online stores from China, you can purchase a popular mini-alarm system with a PIR ALARM GSM module.

The principle of operation of the alarm system with the PIR ALARM GSM module

The mini-alarm itself is a small block, the size of which is smaller than a box of matches. It has a built-in infrared motion sensor, as well as a GSM module, into the slot of which a SIM card is inserted. Such an alarm unit can be powered from a small rechargeable battery or from an external source connected by a USB cable. Most often, such a mini-alarm system with a PIR ALARM GSM module is used at home. It is ideal for home safes or cabinets. It is enough to put such a device in a safe, close the door, and use an SMS command to arm it. As soon as the safe door is opened, the infrared sensor will work and send the corresponding message using the GSM module to the number of the safe owner. At the same time, a call will be made to the mobile phone number, with which it will be possible to listen to the protected area through the microphone in the gadget. This will help to understand the situation in the security zone. We hope that we explained the functionality of the mini-alarm system with the PIR ALARM GSM module well enough. Many motorists have already guessed that such a mini-alarm system can be used in a car.


 Here is a small block that can be used not only in a safe, but also in a car.

PIR ALARM or its analogues will be useful to the owner of the car if he leaves it out of reach of communication with the remote control of the car alarm, which is already installed. Moreover, such a mini-alarm system is more effective, since it will transmit to the owner’s phone all the sounds that occur at the time of a car break-in: crackling plastic, rustling, rattling tools. However, motorists should still be aware that even such a device is susceptible to jamming. Accordingly, an alarm with a PIR ALARM GSM module is a rational and cheaper solution if the standard car alarm is not equipped with a GSM module. We are just informing you about a cheaper alternative.

Alarm installation with GSM module PIR ALARM

The very small dimensions of the alarm device block with the PIR ALARM GSM module allow you to install it in an inconspicuous place in the car. The device itself does not have an on/off button. It starts working as soon as a sim card has been installed in the unit. Also, the device block has an SOS button on the body, which is convenient when using this alarm in the form of a pocket tracker with an alarm button. Such a block can be worn by children. If something happens to them, they can press the SOS button and the phone will ring on their parents' phone.

Typically, the alarm unit is installed on double-sided tape. More often this is done in a place accessible to the owner, but non-standard for robbers. The infrared sensor must be directed towards the driver's seat.

After installing the alarm unit with the PIR ALARM GSM module in the car, it is necessary to bind the SIM card numbers to each other. The owner calls from his phone to the SIM card inserted into the alarm unit. With this call, the SIM card is bound. After the call, you must send an SMS with the text 1111 to the SIM card of the alarm unit. In response, the owner will receive a message with the text: The PIR alarm opened. From this moment, the alarm system with the PIR ALARM GSM module starts its work in the normal mode. With the help of SMS, it is also possible to disarm the alarm unit. To do this, send an SMS with the text 0000.


 This is what the SOS button looks like on the device block.

Also, owners should be aware that the built-in battery in cold weather will last a maximum of two days. That is why it is necessary to take care of the constant power supply of the alarm with the PIR ALARM GSM module. It may be necessary to purchase a Power Bank to connect the alarm device with a mini USB cable.

GSM alarms are one of the most effective security systems used to support security at facilities such as Vacation home, etc. Equipment of this type allows you to continuously monitor security and, if threats are detected, promptly report this to the owner and the security service or the police. The transmission of the alarm signal is carried out using cellular communication, for which a GSM signaling module is used.

Functionality and operation

Module burglar alarm is one of the key devices that are part of the GSM alarm system. Thanks to this electronic unit, continuous communication with sensors and sensitive sensors at the protected facility is ensured, and an alarm is promptly sent to mobile devices or stationary telephones associated with the alarm. The electronic module supports:

  • automatic transmission of SMS or MMS messages to the numbers stored in the SIM card;
  • dialing to mobile or landline numbers that are stored in the module's memory;
  • transmission of information (video, audio) about the state of the controlled object to mobile devices (phones, smartphones, tablets, etc.);
  • LED indication of own status.

The GSM module for security alarm operates by receiving information from a system of sensors that are located in controlled areas at the facility. Upon receipt of a corresponding signal from them, the functional diagram of the module, according to the established algorithm, dials or generates a threat message. For this purpose, one or two cellular networks of mobile operators are used (depending on the number of supported SIM cards).

To connect the GSM module to the sensors, a wired backbone (in many cases it is a twisted pair) or wireless high-frequency channels is used. The connection method depends on the design of the sensors used - wired or wireless.

How to create a GSM module yourself?

Effective security based on cellular communication is quite possible to do on your own - this will require a system of sensors and an appropriate electronic unit for transmitting a signal using cellular communication. You can either buy them in the store or create your own. Do-it-yourself GSM alarm module can be created using an unused, but still working mobile phone.

To do this, you need a phone that supports the function of speed dialing a programmed number by pressing and holding one of the buttons. Having set up a quick call, you should solder conductors to the contacts of the active button, which are connected at the other end to the sensor or group of sensors used. When the sensitive element is triggered, the conductors will switch, which will be equivalent to pressing and holding a phone key, and, accordingly, making a call to the subscriber.

If the mobile phone does not receive or is not available at hand, you can purchase a ready-made universal GSM module . Such devices are intended both for installation in existing security and tracking systems for objects, and for building new configurations. Communication of such a module with sensors and other systems is carried out both using standard digital inputs and via Rx, Tx serial ports.

In the process of setting up such electronic devices, you need to register telephone numbers to which information should be transmitted. The module also supports the ability to modify its commands and configure it for other functions. This will be required when connecting various functional sensors that monitor temperature increase, gas leakage, smoke and fire.

Overview of some models

Depending on the model of the module, the security unit GSM alarms can support various additional options. Let's consider some of them on the example of Xital and Excellent devices.

Distinctive features possessed by the GSM module Ksital is the ability to remote control and control of various equipment incorporating an electronic unit with a controller that can be controlled using a current signal. Using Xital modules , you can control and monitor the operating parameters:

  • heating boilers;
  • gas equipment;
  • freezers;
  • refrigeration units, etc.

"Note!

Also, Xital devices can be installed in server rooms to control temperature regime and monitoring the security of IT equipment.

The listed functions are supported by the Xital system in parallel with its main task - the protection of the controlled object.

Unlike GSM modules Xital, Excellent devices have other optional features. These electronic units are designed for use in the car security system. Practical use such devices will reliably protect vehicle from car thieves and thieves. Distinctive feature owned by the Excellent GSM module is the ability to remotely start the engine using mobile device. This feature is especially in demand in winter.

Not all possibilities of modern GSM modules are listed here. Depending on the task to be solved, it is possible to choose the most suitable device that will guarantee a high level of safety at the facility, as well as provide the ability to remotely control its executive systems and manage their operation.
