Abstract
This design is a system which makes use of wireless technology to control circuit. The main engine of the system is composed by STC89C52SCM, key, DS1302 (clock chip), 315Mtransmitter module and Light detection circuit. The slave is composed by 315M wireless module and piezoelectric infrared human body induction module. The system constitutes a complete signal processing circuit through the remote wireless communication network, the single-chip microcomputer control center and LED lamp control terminal. It can not only save energy and money, but also can improve target localization accuracy and reduce management costs, so that offer facilities for people’s work and life. After debugging, this design has reached all the expected requirements.
