Design of Smoke Alarm System Based on STM32

:With the rapid development of economy and the acceleration of urbanization, the loss caused by fire is more and more serious, so the effectiveness and accuracy of fire detectors are very important. In this paper, we design and implement a smoke detection with STM32and GSM/GPRS. The alarm system is based on multi-sensor fusion. The reliability of the system is tested by data simulation and scene simulation. The smoke alarm system has strong ability of fire monitoring and alarm, and has the advantages of small size, strong practicability, simple operation, timely alarm and so on.
