Abstract: The design of the control system of intelligent alarming eye protection table lamp, with the single -chip puter
STC12C5202AD as the controller, using ultrasonic technology to measure distance. The hardware design of the system is achieved by
STC12C5202AD single chip, MAX232, NE5532, LM393, SFR, buzzer and so on. And the software design of the system is plished by
Keil uVision3 software development environment. The system can be set alarm distance freely, alarm automatically within alarming range and
switch from different alarming methods automatically and so on. It can rectify the sitting posture and protect the eyesight of people.
Key words: single chip puter; untrasonic; alarm; software design
