This document describes an advanced remote accident information system using GSM that monitors vehicle conditions during travel and informs family members if an accident occurs. The system uses a piezoelectric sensor to detect vibrations during an accident and sends a signal to a microcontroller. The microcontroller processes location information from a GPS receiver and sends an SMS alert about the accident and location to a predefined mobile number using a GSM modem. This allows the system to immediately alert emergency services to the accident location.
