ABSTRACT
The main motto of the project is to use the wireless technology effectively for the
automotive environments by using the GSM Modem used in sending sms in case of theft
intimation. The main scope of this project is to stop the engine of an automobile automatically,
this can be done when ever a person trying to theft at that time sends an interrupt to a
programmable microcontroller of 8051 family, When someone tries to steal the car then
microcontroller gets an interrupt and orders GSM Modem to send the sms, the owner receives a
SMS that his car is being stolen then the owner sends back the SMS to the GSM modem to ‘stop
the engine’, while the vehicle will be stopped The control instruction is given to the
microcontroller through interface, the output from which activates a relay driver to trip the relay
that disconnects the ignition of the automobile resulting in stopping the vehicle.
The power supply consists of a step down transformer 230/12V, which steps down the
voltage to 12V AC. This is converted to DC using a Bridge rectifier and it is then regulated to
+5V using a voltage regulator 7805 which is required for the operation of the microcontroller
and other components.
