GSM based automobile security system Introduction
This paper presents one of the emerging applications of the GSM technology. We present the design of a stand- alone embedded system that can automatically guard the automobile (CA ! door loc"ing and engine loc"ing system using automatic sensor technology. emotely the system allo#s o#ner to monitor and control his automobile $ia mobile phone set by sending commands in the form of SMS messages and recei$ing the loc"ing system status. The hard#are architecture consists of a standalone embedded system that is based on % bit microcontroller& an interface and a dri$er circuit connects the sensors to the microcontroller.

'ro(ect description)
In this pro(ect& the sensors are controlled #ith the help of a cell phone. The system uses sms facility to gi$e the commands and recei$e the status from the recei$er. The mobile user sends a secret code #ith control data. In the recei$er section& GSM modem recei$es the commands and sends the signal to the microcontroller. The micro controller $erifies the secret code and performs the command functions. The controller also triggers the sensor circuit through dri$ers.
