Abstract：The design of an intelligent LED lighting control system is introduced. According to Doppler Effect, by using a microwave based motion sensor HB100, moving targets could be detected and Doppler waves would be generated consequently. After amplifying and filtering the output signal of HB100, by using logics and algorithms described in this paper, a STC89C52 microcontroller system could control the street lighting system to illuminate the moving targets accordingly on time. In the experiment, tow rows of LED lights were used to simulate the street lighting system and by lighting the LEDs successively according to the moving target’s position which is predicted by the system, energy-saving lighting is achieved. The latency and the interval of the lighting behavior could be adjusted according to the needs from real deployments.
