Abstract: In view of the current situation that the number of people in the classroom is small and the lighting area is large, and the number of classroom personnel cannot be accurately searched, this paper designed a passive detection of energy saving lighting system. The system takes STC12C5A60S2 as the core, proposes a method to detect the number of people by using two groups of infrared tubes separated by each other, and uses photosensitive resistance to detect the intensity of ambient light, so as to determine whether to turn on the light and the number of people according to the intensity of light and the number of personnel intrusion. The clock chip can be used to control the start and end time of the lighting system to avoid the management of classroom by classroom inspection; The system can measure the classroom temperature, and upload the temperature information and the flow information to the cloud platform, which is used for students to visually query the comfortable and idle self-study classroom and teachers to statistically check in. After testing, the system runs stably and achieves the purpose of intelligence, high efficiency and energy saving.
