Currently on the market, most of the power supply are wired, usually you can also, in a multi-user centralized control applications, the use of wired switches focus to control each users power switch (such as student dormitories, intelligent community, school computer room and experimental room), raw materials and construction, it will be a lot of money. Moreover, from the overall aesthetic appearance of the project is concerned, it is not beautiful, if the power of wireless control, you can save a lot of expenses and reduce some unnecessary trouble. The design is based on single chip wireless control system for laboratory equipment. The design uses a remote control switch to the 315MHz frequency stabilization of radio-controlled components and other peripheral components assembled. Microcontroller can control a variety of laboratory equipment. The design is divided into the wireless module PT2262/PT2272 coding circuits, power switch and microcontroller control section. The MCU sends the corresponding control signal sent to the data input of PT2262. By the PT2262 encoding and modulation in 315MHZ carrier, antenna out after a high-frequency amplification. Then the signal received by the receiver board, after two LM358 high-gain amplification into the PT2272 to decode the output sent to the microcontroller, the microcontroller according to the operation signal to control the corresponding el
