Abstract: A new type of intelligent infrared reflective optical switch is presented in this paper. The switch uses remote infrared control receiver module (IRM) as the receiving device, and is simplified in the circuit in this way. The output signals of IRM are transferred into the microprocessor directly. Microprocessor as smart control unit  provides the infrared receiver a feedback-response function in emission or reception process. Dynamic light-intensity control technology is applied to restrain the interfering signals from unstable reflections due to vibration and uneven surface reflection in the moving process of the object measured and the reliability of the detection is improved. The design principle and method are introduced .The circuit and reference program are presented too.

Keywords: infrared receiver module; microprocessor; photoelectric proximity switch; sensor
