According to the present peoples needs and market needs, I designed a microcontroller-based multi-channel wireless burglar alarm system. The system is the signal processor, sensors, wireless transmission module, the alarm circuitry in a small system, to achieve signal detection, signal processing, signal transmission of the new generation of automatic intelligent wireless alarm systems. This system uses the wireless transmitter and receiver module, the received signal is processed through the decoder chip sent to the microcontroller, the microcontroller processing, transmission to the alarm display circuit and a series of actions. Main control module: the sensor is passed through the sensor body, and the formation of high-low transition of the output to the microcontroller for processing, and ultimately determine the signal, delay, display, alarm and other functions. The system for the detection of alarm, can simultaneously detect multiple points, when detected one or more points have the alarm signal, can sound the alarm and LED display location, to achieve the intelligent alarm control.
