In this paper, with STC89C52 SCM as the core, light sensors are used to detect environmental change, and through in-frared sensor module, signals of the movement of objects are in-put into the SCM in the form of high and low electrical level, and through the input situation of infrared light, directions of objects are determined, thus the switch of LED light is controlled.
