loT-Enabled Smart Helmet for Safety and Accident Detection

An intelligent helmet for the safety of the motor-cycle riders has been developed that incorporate the cutting edge technologies. The helmet has the modules like alcohol detection system having M Q-3 alcohol sensor, RFID based lock system, voice recognition system to open the helmet visor, accident detection through accelerometer which can detect sudden changes in acceleration and GSM enabled accident notification system to send alert notification to the emergency contacts. Different sensors are used in various modules to do the specific task of the modules. A prototype has been prepared by assembling different sensors, servo motor, motor, relay and microcontroller. After assembling, the circuit has been tested to check the performance of the prototype which is quite encouraging. Also, the low power consumption of the microcontroller ensure operating longer without sacrificing the performance.
