Abstract: This article introduced the electric appliance remote control characteristic in detail, the structure and the principle of work. The infrared remote control technology is one kind carries on the point-to-point communication using infrared the technology, It is takes infrared the carrier the remote control way. Due to the long-wave infrared wavelengths than radio waves, Therefore, in the manner of the use of infrared remote control, does not interfere with the normal operation of other electrical appliances, It also will not affect radio equipment nearby. Modular design of the program can be broadly divided into two modules: infrared transmitter and infrared receiver module. I designed a remote control that can be controlled by the five electrical power switch and lights on all the way to adjust brightness. The design can control a wide range of household electrical appliances, saving energy, a very simple operation, scalability, and as long as a little change can be used to increase other functions.
Key Words: Remote controlling circuit; Infrared emission; Infrared receiving; SCM
