This article on the system modular processing, system hardware circuit including host, infrared emission, the power modules, LED lamp instruction module four major parts. The mainframe mainly adopts singlechip microcontroller smallest system posed STC89C52, infrared emission is through the monolithic I / O mouths modulation 38KHZ signal, driving the infrared diodes, make its send lubricious infrared, as control signal. When detect person, infrared reflected back by infrared integration accept tube, received, infrared integration after receiving
