The Application of Infrared Remote-control on Energy-saving and the Wireless Operating System
Abstract：An remote-control system of the based on AT89C2051 micro-controller was introduced. Through exploring the encoding rules of nearly 100 remote-controller signals，The encoding methods of the different remote-controllers is found, this method uses the remote-controller of the electrical appliance itself to switch off the power supply, and achieve the function of energy-saving and the wireless operating as well.
