Abstract

An intelligent energy-saving system is designed in order to save energy for the lighting system for classroom, which is composed of single chip, artificial wireless control module, pyroelectric infrared detection module and sunlight intensity detection module. The system can run in two ways of manual control and automatic control. In the case of automatic control, when the light intensity is less than the preset value and there are some people in the classroom, the lamp will light-on automatically. The lamp will remain lighting-on in a period of time after the leaving of people, and the delay time can be set according to the actual situation.
