Smart Helmet with Safety and Monitoring Features

– Smart Helmet with Safety and Monitoring Features, this project seeks to promote the safety of cyclists riding two-wheelers using accident-preventing real-time monitoring and controls. In particular, the project utilizes a bike control unit featuring an ESP32, LCD screen, DC motor controlling bike movement, MPU6050 tilt sensor detecting any accidents, GPS tracking device, and an RF433 receiver. A smart helmet control unit comprises the following components: RF433 transmitter, limit switch that detects whether or not the cyclist is wearing a helmet, and an alcohol detector to measure the sobriety level of the cyclist. Information concerning whether the helmet and alcohol detector indicate that the cyclist is sober or not is transmitted from the smart helmet unit to the bike unit. Apart from providing accident-preventing control, the project also features accident monitoring capabilities. The bike unit transmits real-time data concerning accident indication, helmet presence, alcohol indication, and GPS coordinates to the Mobile Application.
