Design of multi-channel wireless remote switch control system for smarthome control system

The system designed in this paper is a multichannel wireless remote switch control system, which uses the single chip microcomputer(SCM) AT89S52 as the core of control and uses the wireless encoding and decoding chip PT2262/2272 as the core of wireless communication. Furthermore, this system includes an expanding design of an infrared human body induction circuit in order to improve the intelligent control to household furnish. System tests show that: The system reliably realizes the wireless remote intelligent control to a variety of household electrical appliances and the display of the status of different household electrical appliances.
