Mother Helmet: sistema embarcado para monitoramento de sobriedade e uso correto do capacete em motociclistas

Abstract

This work presents the development of a system called "Mother Helmet", a helmet with an embedded system designed to enhance motorcycle rider safety. The system consists of alcohol sensors, flow sensors, and a push button, which perform sequential tests to verify the rider’s sobriety and the correct use of the helmet before allowing the motorcycle to start. Communication between components occurs via Bluetooth, connecting the transmitting unit, located in the helmet, to the receiving unit, which must be integrated into the motorcycle’s electrical system. If any of the conditions are not met, the vehicle’s ignition is blocked. The prototype development included the integration of sensors, microcontroller programming, and bench testing, allowing the system’s functionality to be validated. The results demonstrated that the sensors can correctly identify alcohol presence, breath verification, and proper helmet use. The project aims to contribute to the reduction of accidents caused by riding under the influence of alcohol and the lack of safety equipment, presenting a viable approach for application in motorcycles.
