Fully Automatic Infrared Pyroelectric Home Burglar Alarm Design

With the continuous development of technology and the improvement of people's living standards, there is an increased focus on safety. Therefore, research on safety prevention and automatic alarm systems is gaining attention in homes, businesses, and institutions. This paper introduces a monitoring and alarm system design based on the DYP-ME003 thermopile infrared sensor. The design is simple, stable, and effective, with strong anti-interference capabilities, a long detection range, a wide detection area, and high sensitivity. Moreover, it is discreetly installed and easily managed. The design consists of software and hardware components, including a power supply, status indicator, STC89C52 microcontroller, buzzer alarm module, LCD module, and the DYP-ME003 human infrared sensor.
