GSM (Global System for Mobile Communications) is an open digital cellular technology used to transmit mobile voice and data services. GSM differs from first generation wireless systems in that it uses digital technology and Time Division Multiple Access (TDMA) transmission methods. GSM is a circuit switched system that divides each 200 kHz channel into eight 25 kHz time slots. GSM operates in the 900MHz and 1.8GHz bands in Europe and the bands 1.9GHz and 850MHz in the USA. The 850MHz band is also used for GSM and 3GSM in Australia, Canada and many countries in South America. GSM supports data transfer speeds of up to 9.6 kbit / s, allowing the transmission of basic data services such as SMS (Short Message Service). Another important advantage is its international roaming capability, which allows users to access the same services when traveling abroad as at home. This gives consumers seamless and equal connectivity in more than 210 countries. GSM satellite roaming has also expanded access to services in areas where there is no terrestrial coverage.

As the crime rate is rising, the security system for vehicles is very essential. In this proposed system, if someone tries to steal the car, the microcontroller receives an interruption through a switching mechanism connected to the system and commands the GSM modem to send an SMS.
The owner gets the SMS that his car is stolen. You can then return an SMS to the GSM modem to stop the engine. The GSM modem connected to the microcontroller receives the message, whose output activates a mechanism that deactivates the ignition of the vehicle resulting in the vehicle stop. The project uses a lamp to indicate the on / off condition of the motor.
Therefore, the owner of the vehicle from anywhere can turn off the ignition of your car. This project can be further improved by integrating a GPS system, which will give the exact position of the vehicle in terms of its latitude and longitude. In addition, this data can be sent to the owner through SMS that can enter this value in Google Maps to obtain the exact location of the vehicle.
