This document describes a wireless accident tracking system that uses vibration sensors, GPS, and GSM networks to detect vehicle accidents and send alerts. When an accident occurs, the vibration sensor detects it and sends a signal to the microcontroller. The microcontroller then switches on the GPS and GSM modules. The GPS module obtains the location coordinates, which are sent via GSM to emergency services. This system allows for quick response in remote areas to minimize accident severity.
