In addition, various lighting has certain use, still continue to use in a well-lit conditions, life will certainly shorten lamp. But the existing molding classroom lighting control system has some problems in the application, need to do research and development in the further. In this paper, a detailed study of the characteristics and needs of school classroom lighting and the existing problems, put forward a kind of automatic lighting control system, using low power microcontroller and field bus technology, on the basis of the improvement, such as switching the light, infrared detection, voice chip operation to control the lamp. The system has the circuit design of data acquisition module, serial communication module, execution etc.. Finally the system is realized in the day light, the classroom regardless of whether anyone lights are not open. In the light is not sufficient, the infrared detection and noise detection to judge whether a person to control classroom lamp control. And in the light of the circumstances, the system enters the surveillance state, if five consecutive detection are not people, a wa
