In order to improve the system, based on control and current methods of how to keep control ， developing intelligent classroom light control system and developed the hardware and software system. This classroom light intelligent control system the theory of the light put forward methods ofon the basis of AT89C52 is developed, which machine of AT89C52 is a major part, and the environment of development is better than before. This system can satisfy the following functions, such as controlling the circuit of illumination, testing and processing daylight signal, testing and processing the signal of human body that illuminates the back track exists, reporting to the warning devices,etc.In order to satisfy these functions, the system adopted the homologous methods respectively, and to the gearing of the system, analyzing how to install，test and run the system. The microcontroller software was...
