Worker & Bike Rider Safety Helmet with Accident Alert and GPS Tracking

Advanced Smart Helmet Accident Detection System with GPS & GSM Alert

The Worker & Bike Rider Safety Helmet with Accident Alert and GPS Tracking is a compact and reliable life-saving system designed to detect head impacts instantly and send emergency SMS alerts with live location. Built using an Arduino Nano R3 (ATmega328), GY-NEO6MV2 (NEO-6M) GPS module, SIM800L GSM module, and a 4-pin tactile impact switch, this smart helmet solution ensures rapid response during accidents for both industrial workers and bike riders.

This innovative project—supported by Bigyan Project—combines safety, IoT communication, and real-time tracking in a simple, battery-powered design. The system uses dual 18650 Li-ion cells with LM2596 buck converters to deliver stable voltage levels for both the Arduino and GSM module. When the impact sensor is pressed due to a fall or collision, the Arduino triggers the GPS module to collect coordinates and sends an SMS alert through SIM800L.

Ideal for construction workers, delivery riders, bikers, and industrial safety applications, this smart helmet boosts personal safety by enabling immediate communication during emergencies.
