Abstract:With the continuous development of the social economy,people pay more and more attention to energy conservation and environmental protection. The traditional lighting methods have high energy consumption and serious waste of resources,which is not conducive to energy conservation and environmental protection. This article is based on intelligent control and energy saving technology, using photoresistance,infrared sensor and sound control sensor to detect environmental information,using STC89C52 as a processor,
using BTN7971 full bridge drive to drive LED lights,using AD conversion to obtain light intensity and convert to the corresponding brightness of LED lamp,achieves the purpose of intelligent control of lighting circuit.
Keywords:STC89C52;infrared sensor;photoresistance;sound control sensor;full bridge driver
