The design of infrared induction automatic mobile portal design and implementation, using infrared sensors as sensor, the detection of radiation to the human body infrared energy change, the conversion of voltage signal, transmitted to the single chip microcomputer, stepping motor as a power device.?Control the rotation of the stepper motor through the microcontroller, so that the door automatically opens, when the door can automatically shut the door. This paper is mainly to achieve infrared detection and control system based on AT89C51 single chip microcomputer. Its advantage is that the hardware circuit is simple, the software function is perfect, the control system is reliable, the performance to price ratio higher characteristic, with certain use and reference value.
