Abstract
With the rapid development of the social economy, the number of motor vehicles is increasing daily. According to statistics, China has ranked first in the world for automobile sales however, this growth has also led to a rise in traffic accidents. Fatigue driving is one of the leading causes of these accidents. To safeguard peoples lives, health, and property, and to reduce traffic accidents caused by fatigue, we have designed a fatigue driving reminder device based on the STM32 microcontroller unit (MCU). The device utilizes a pressure sensor and a timer for data collection. The STM32 processes this data to determine when the buzzer should sound an alert. Additionally, the device incorporates a photoresistor to measure external light levels when these levels are low, an LED light is activated to remind the driver.
