Design of intelligent safety helmets based on microcontroller

This design aims to create an innovative intelligent safe riding helmet, which integrates embedded technology, sensor technology, and human-computer interaction technology to comprehensively improve cycling safety and comfort. The core technology solution is based on the STM32F103C8T6 microcontroller, combined with infrared module, pulse and heartbeat detection module, raindrop detection module, OLED display module, vibration alarm module, and voice prompt system, to achieve functions such as head wearing detection, real-time pulse monitoring, weather condition perception, safety warning, and information exchange. This smart helmet can automatically recognize the wearing status and continuously monitor the health and environmental information of cyclists through multi-mode sensors. In the event of abnormal conditions, it promptly sends out alarms and provides necessary assistance to build a comprehensive safety protection system for cyclists, while optimizing the riding experience and improving their safety and comfort.
