THEFT INTIMATION OF THE VEHICLE OVER SMS TO OWNER WHO CAN STOP THE ENGINE REMOTELY


PROJECT DESCRIPTION

The aim of this project is to use wireless technology to intimate the owner of the vehicle about any unauthorized entry. This is done by sending an auto-generated SMS to the owner. An added advantage of this project is that the owner can send back the SMS which will disable the ignition of the vehicle.

As the crime rate is going up, security system for vehicles is extremely essential.

In this proposed system if someone tries to steal the car, the microcontroller gets an interrupt through a switch mechanism connected to the system and commands the GSM modem to send an SMS. The owner receives the SMS that his car is stolen. He can then send back an SMS to the GSM modem to ‘stop the engine’. The GSM modem interfaced to the microcontroller, receives the message, the output of which activates a mechanism that disables the ignition of the vehicle resulting in stopping the vehicle. The project uses a lamp to indicate the engine ON/OFF condition.
