Abstract
In order to overcome the problems of traditional fire prevention and theft system, such as expensive price, complex installation, beautiful impact and troublesome aftersales service, this paper proposes an intelligent fire prevention and theft alarm system based on STM32 single chip microcomputer and GSM short message module. The data is collected in real time through the sensor module and processed by the microprocessor. If any abnormality is found, Sound and light alarm and send to the user's mobile phone through GSM short message for alarm. This method has high cost performance, powerful function, good real-time performance and wide application range. The experimental results show that the system is simple, convenient, reliable and accurate, and has practical and popularization value.
