Design of Self-serve DUI Detection System Based on STM32

Drink driving accounts for a very large proportion of accidents arising from vehicle driving, which seriously threatens people’s life safety This question designs a DUI detection system based on STM32F103C6 microcontroller. Combine IOT technology with machine vision technology to contribute to social security. The MQ-3 alcohol concentration sensor is used to detect the concentration level of the driver’s breath alcohol content, OpenMV is used to detect the closing of the driver’s eyes, and the information is summarized by the STM32 microcontroller and a warning reminder is issued by voice to reduce DUI and reduce the risk of accidents.
