Under the premise of both the usage characteristics of electricity and lighting need in school classrooms, this paper aims to design an automatic lighting control system carried out bya STC89C52 microcontroller and then to position the object in the teaching buildings of universities for the main purpose of the realization of turning off the light when noone is inor adjusting the illumination intensity according to the surrounding lighting strength, which can be broadly classified into personnel detection, light intensity detection, the modules of system control and lighting display, for mon goal to realize the required function of the system so as to achieve the purpose of energy-saving, convenience of administration, and soon. This paper mainly presents an introduction of the hardware and software design of each part in the automatic lighting control system. By way of the designation of each part, the understanding of the microcontroller system can be strengthened and the re
