This Project presents an automatic vehicle accident detection system using GPS
and GSM modems. The system can be interconnected with the car alarm system and alert
the owner on his mobile phone. This detection and messaging system is composed of a
GPS receiver, Microcontroller and a GSM Modem. GPS Receiver gets the location
information from satellites in the form of latitude and longitude.
The Microcontroller processes this information and this processed information is
sent to the user/owner using GSM modem A GSM modem is interfaced to the MCU. The
GSM modem sends an SMS to the predefined mobile number and informs about this
accident. This enable it to monitor the accident situations and it can immediately alerts
the police/ambulance service with the location of accident.
The project is built around the AT89S52 micro controller from Atmel. This micro
controller provides all the functionality of the SMS alert system. It also takes care of
filtering of the signals at the inputs.
