Iot Based Multi Sensor Helmet for Real Time Accident ,Alcohol Monitoring,Gps Tracking and Emergency Alert System with Ignition Interlock

The increasing number of road accidents, particularly involving two wheeler riders, highlights the urgent need for intelligent safety systems. This project presents an IoT - based multi-sensor smart helmet designed to enhance rider safety through real-time accident detection, alcohol monitoring, GPS tracking, and an emergency alert system integrated with an ignition interlock mechanism. The proposed system incorporates multiple sensors, including an accelerometer and vibration sensor for detecting accidents, an alcohol sensor to monitor the rider’s sobriety, and a GPS module for real-time location tracking. A micro-controller processes sensor data and communicates with cloud platforms using IoT technology. In the event of a crash, the system automatically detects abnormal impact patterns and sends an emergency alert message along with the rider’s location to predefined contacts or emergency services.
