Multi-Functional Anti-Theft Alarm System Based on DYP-ME003

With the rapid advancement of science and technology and increasing societal awareness, environmental security issues have gained the focus of social concern, prompting people to pay more attention to the safety and security of living and working environments. This paper presents the design and implementation of a multifunctional anti-theft alarm system based on the DYP-ME003 sensor. The system utilizes the STC89C52 microcontroller as the central controller, processing signals from the DYP-ME003 human infrared sensor and the DHT11 sensor. It records intrusion events in an external AT24C04 memory chip and displays real-time temperature, humidity, and clock information. The system is practical and user-friendly, incorporating multiple functional modules, including infrared alarms, environmental monitoring, and clock display. Additionally, the system exhibits high sensitivity, enabling accurate data monitoring and providing a reliable security mechanism.
