A safe driving system based-on STM32

With the increasing popularity of private cars, the incidence of traffic accidents has increased year by year. Among them, drunk driving and fatigue driving account for a large part of the reason. Aiming at this situation, the safe driving system offers a practical and effective solution. The system consists of three modules: anti-collision, anti-drunk driving and anti-fatigue driving: STM32 is used as the core to expand outward. The HC-SR04 ultrasonic range finder is used to detect the distance from the front obstacle. The side-heated semiconductor alcohol gas sensor MQ-3 is used to detect the alcohol concentration in the air. Collect and process the facial information with the Raspberry Pi, and issue a prompt when the driving time reaches the upper limit for continuous driving. As a result, this system achieves the three major functions: anti-collision, anti-drunk driving and anti-fatigue driving. The safe driving system puts prevention first, which can reduce the incidence of traffic accidents effectively.
