| Abstract: The current house intrusion detection system through cable connections has some obvious disadvantages,such as unreliable performance,high cost and complicated installation.This paper analyzes and designs a house intrusion detection system based on Pyroelectric Infrared Sensor (PIR).The system applies the HC-SR501 infrared sensor module to detect instructions,uses the AT89C51 single chip microcomputer to process and control signals,employs the nRF24L01 wireless module to implement wireless communication among nodes.The paper firstly designs the overall scheme of the system,and then designs the hardware and software according to the composition and functions of the system.The experimental results show that the system has high-level accuracy and real-time capability of intrusion detection with high stability,low power consumption,simple installation and good practicability. |
