The hidden antitheft devices installed, thieves can not easily be found, and it signals processed through the SCM system to facilitate munication and PC, to facilitate the unified management of multiple users. The design includes two parts, hardware and software design. Hardware includes single chip control circuit, infrared sensor circuit, driving the implementation of the alarm circuit, LED control circuit and other ponents. 51 series processor AT89C51, the whole system is under the control of the system software to work. Keywords: microcontroller。 infrared sensor。 data collection。 alarm circuit 目 錄摘要1引言 4 42 基礎(chǔ)知識(shí)介紹4 4 PIR的原理特性5 AT89C51單片機(jī)簡(jiǎn)單概述18
