Abstract

By consolidating many real-time monitoring capabilities into a single, affordable unit, the suggested smart helmet system is an Internet of Things (IoT) based safety solution that aims to improve the protection of riders of two-wheelers.  Based on an Arduino Uno microcontroller, the system makes use of an infrared sensor to identify when a helmet has been worn, a multi-gas meter to measure blood alcohol content, and an accelerometer to identify when an accident has occurred.  The device utilizes a relay module to disable vehicle ignition in the event that the helmet is not worn or if alcohol is detected.  The system has a GPS module that automatically tracks the rider's position in case of an accident and a GSM module that notifies pre-set contacts of the rider's whereabouts.  This smart helmet is a small, practical, and energy-efficient way to reduce road fatalities and improve emergency response times. It uses both proactive and reactive techniques to keep riders safe
