Intelligent Table Lamp Based on Single Chip Microcomputer

Abstract At present, modern smart home is increasingly favored by people, and the functions of intelligent desk lamps become diversified with demand updating. In process using lamps, poor sitting posture or overuse eyes may cause vision loss physical pain. Therefore, it great theoretical significance practical value to actively explore develop an lamp low cost automatic dimming, correction, reminder rest, energy conservation environmental protection. designed in this paper, STC89C51 microcontroller used as core controller, BH1750 light sensor module detect current ambient intensity, pulse width modulation (PWM) technology control brightness for TB6612 motor drive. The infrared probe personnel detection. When detects that someone approaching, will be automatically turned on through relay module. no one detected, controls turn off power off. very convenient use. It can not only save electric effectively, but also solve problem touching dark potential safety hazard people switching lamp. has good application market prospects.
