It introduced the Selection of the core chip, the external circuit connections, chip and the connection between the circuit chip, program design methods and the corresponding software. 7805,7809 chip system power output by 5 V, 9V voltage regulator module to the system through the power supply. The whole design is modular thinking, host AT89C51 used to achieve control, by the pyroelectric sensor and vibration displacement sensors for residential analog signal (the human issued by the infrared signal from the vibration signals, and so on) for automatic monitoring, When detected abnormal circumstances, producing a digital signal input SCM, the MCU according to the input signal and output to the buzzer alarm, to respond to treatment. Reset circuit using lowpower, fourpin IMP812 monitoring chip. System hardware circuit simple, easy to install, simple operation, and has the advantage of low cost, applicable to all types of residential and the crowd. Key words: sensor； MCU； alarm system III 目 錄 摘要 ...................................................................................................................
