Abstract

This project presents a GPS and GSM based accident alert system that automatically detects accidents and sends emergency notifications. The system uses Arduino Uno and an accelerometer such as ADXL335 to detect sudden impacts. When an accident occurs, the location is obtained using the NEO-7M GPS Module and an alert message is sent through the SIM800 GSM Module to a predefined mobile number. This system helps provide faster emergency response and improves road safety .
