An IoT-Based Smart Helmet for Riding Security and Emergency Notification

A motorbike is more commonly utilized than other types of vehicles due to its affordability. On the contrary, this is the riskiest vehicle because driving too quickly or when intoxicated can result in an accident. The number of daily traffic accidents, including bike accidents, in Bangladesh is increasing tremendously. Without a helmet, the impact of a high-speed collision on a motorcycle is exceedingly dangerous. A helmet may even save a life by reducing the effects of a collision. In many zones, bikers are required to wear helmets when riding their motorcycles, but they take the chance not to wear helmets. To prevent accidents, we have proposed a smart helmet system that will minimize the chances of accidents occurring. The system is divided into two sections: the mobile application, where the rider will monitor the current status of riding a motorcycle, and the helmet circuit, which is the core segment that takes input from the environment. The helmet circuit initially includes a NodeMCU, an alcohol detection sensor, a crash sensor, a motion sensor, etc. The automotive circuit includes a tachometer to measure the bike's speed, and the mobile application section shows the overall performance result to guide the biker. The helmet circuit sends the detected signal to the mobile application, where the biker can see the present status of system sensors, whether alcohol, motion, or overspeed are detected or not. The mobile application section sends a notification to the nearest police station, hospital, and default relative's mobile.
