防盗报警功能电路板设计大赛，热释电红，传感器，红外探头，超声波。-Anti-theft alarm circuit board design competition, pyroelectric red sensor, infrared sensor, ultrasound.

基于PIC单片机、无线收发技术和热释电红外传感器的被动式红外报警系统-PIC-based microcontroller, wireless transceiver technology and pyroelectric infrared sensor passive infrared alarm system

以热释电红外探测器、光亮度及声控传感器做为照明区域的感知器件，进行信号采集，将采集信号通过转换电 路转换后传到STC12C5628AD 单片机，经单片机处理后的控制信号控制驱动电路。根据AC LED 电路的特点，驱动电 路以双向可控硅做为核心器件进行设计，系统可实现AC LED 照明的智能开启及亮度调节。经实际电路测试，电路工 作稳定可靠，达到了设计要求。-Pyroelectric infrared detectors, brightness and voice sensor as
