THE DESIGN OF AN EYE-PROTECTION DESK LAMP BASED ON STM32

In this paper, we design an intelligent eye-protection desk lamp based on the STM32 chip. The lamp uses a human body infrared sensor to detect the presence of a person near the lamp. It employs ultrasonic waves and a photoresistor to calculate the distance between the person and the lamp, and to gather information about the surrounding light. A voice module is used to broadcast prompt messages. This design enables the lamp to automatically switch on and off, correct the users sitting posture, adjust its brightness automatically, and provide rest prompts.
