SCM-based Infrared Remote Control Switch Abstract: This paper employs the principle of external interruption in SCM to design a remote control switch based on general infrared remote control system. In this design the infrared remote control receiver is controlled by SCM AT89C51, that is, when the integrated infrared receiver receives infrared remote control signal, the light signal will be turned into electronic one which is consequently amplified, demodulated, filtered and transferred into SCM AT89C51 to be identified, decoded and proceeded correspondingly, so as to control the circuit.
