Disclosed in the utility model is an infrared-sensor-based automatic control system for building illumination. The automatic control system comprises a single-chip microcomputer, more than one set of human body detection and signal processing circuits, more than one set of alternating-current power control modules, a slave machine address storage circuit, a serial port communication module, and a PC host. From the perspective of the energy conservation, the automatic monitoring system of the infrared sensor is used in the building illumination intelligent design and advantages of powerful automatic control function, high flexibility, convenience, and low cost are realized, so that the system is suitable for modification of the illumination system of the building. A pyroelectric infrared sensor is used for monitoring the human body; an operation amplifier is used for carrying out amplification and rectification on a collected signal to generate a control signal; and an actuator carries out turning on or off on illumination equipment in a certain room automatically. Therefore, turning on or off of the illumination equipment in an area is controlled according to the staff situation, thereby realizing energy conservation well.
