Design of an Intelligent Fire and Anti Theft Alarm System Integrating Multiple Sensors and GSM Communication

In response to the increasing demand for safety protection in work and living environments, an intelligent fire and anti-theft alarm system that integrates multiple sensors and GSM communication has been designed. The system is centered around temperature, smoke, and infrared sensors, which collect real-time environmental parameters and process the data through an embedded processing platform. When an abnormal situation is detected, the system can not only issue a warning through the local sound and light alarm, but also remotely send the alarm information to the user's mobile phone in the form of SMS through the GSM module, achieving multi-channel and timely security warning. The system hardware includes power supply, temperature and smoke sensors, infrared sensing, alarm and communication modules, etc. The software part is programmed in C language, and the sensor data is analyzed and processed through logical judgment to control the collaborative work of various alarm devices. Through actual testing, the system can achieve intelligent alarm for fire and illegal intrusion, with the advantages of simple structure, low cost, and rapid response, which meets the development needs of intelligent security systems.
