In today's world we are surrounded by a large number of hardware, home, office equipment, all kinds of security and safety, industrial and semi-equipment: sensors, access systems, various measurement and control systems, actuators, etc. Many of which require constant monitoring, control, attitudes of certain parameters, or to collect data, measurements, etc. The vast majority of cases is required to transfer data or control signals from / to these devices. This is what is called M2M technology, communication, communication: machine-to-machine, mobile-to-machine or machine-to-mobile. GSM (wireless) technology already provide the possibility of such data and control signals. We can only "make" these wireless technologies to manage equipment. M2M technology has already become neotemlemoy part of many business and technological processes. Application of M2M technology can be found at almost every step, and the application of M2M technology is constantly growing. Here are just some of the scope of M2M technology:

• Vehicle GPS

• Automotive

• Personal Monitoring System

• Guard System

• Home Appliance long distance control and
  monitoring

• GSM Video

• Vending machine, Cash Machine, Automatic Gasoline Station

        The proposed system is a wireless control center designed for remote monitoring and management of physical parameters (eg temperature or pressure), as well as monitoring the situation and control mechanisms

Рис. 1. The wireless monitoring and control

       Monitoring allows for rapid regulation of values of physical quantities and position of mechanical elements. Remote data collection is produced by GSM modem Telit Communications SpA GSM / GPRS / Edge modules and terminals company Telit intended for reception and transmission of digital data modes, GSM, GPRS and Edge, make voice calls, exchange of faxes and SMS messages. Office of the modems via AT commands via serial port (UART or RS-232). Received from an external control device (microcontroller or PC) AT command, the modem executes it and gives back to the serial port communication on the implementation (if it is stipulated in the team). Among the AT commands are commands to configure the modem connection, receiving a report on the status of the modem and a cellular network, wealth management lines of I / O ports and others. After establishing the data connection, the modem switches to the mode of transmission. Further, he sees everything that sends to the serial port external controller as data and transmits them to the modem, with which the connection was established. Also, the modem may be responsible for reporting current events - the incoming call, determining the number, you receive SMS, the connection and some others.
To reduce the cost of a finite system company Telit offers modems, software which contains a shell programming language Python (Python). These modems can operate without an external microcontroller, but only under written in this language program that is loaded into the internal flash memory modem. Same purpose (to reduce the cost of the final product) are used and modems with integrated receiver GPS. Manage integrated GPS receiver is made through a special AT commands and receive certain coordinates possibly in the form of response to the command, and the form of maxims NMEA output serial port receiver GPS.
The presence of the programmable inputs / outputs allows using the GSM-modem to control external circuits such as relays, actuators, and implementation of software IIC interface makes it possible to connect to the modem devices having this bus for communications. Such devices may be video camera, camera, sensor teperatury, humidity sensor, etc.
Send data via GPRS or SMS.
