摘　　要：基于单片机的实验室火情自动报警扑灭器以STM32作为控制核心,通过MQ-7烟雾传感器检测烟雾浓度,温度传感器检测温度。烟雾传感器和温度传感器的线传输模块将信息传输到STM32单片机,确定实验室环境的基础情况,识别环境的温度是否变化,让单片机对烟雾传感器、温度传感器等采集到的信号进行处理,并产生相应的报警明灯,最终对喷气装置开关和发声报警装置开关进行控制,实现喷气灭火并伴随声音报警。With the development of technology and education,laboratories are used more and more frequently,and more attention is paid to the safety of researchers in the laboratory.Although the laboratory is equipped with fire extinguishers,the fire fighting system with perfect measures is either too heavy or too expensive,and the low price is often only fire extinguishers,which can not meet the daily use of ordinary people,and can not meet the intelligent requirements of automatic fire fighting.In view of this phenomenon,in order to effectively prevent the fire safety hazard in the laboratory,this paper designed the automatic fire extinguishing device based on STM32 SU,aiming to meet the automatic fire extinguishing requirements of the laboratory,and then meet the majority of ordinary people.In order to realize flexibility,the system realizes the signal monitoring with the smoke sensor and temperature sensor,processes the smoke sensor and temperature sensor,and produces the corresponding alarm light,and finally realizes the control of jet switch and sound alarm device,and realizes the function of jet extinguishing and accompanying sound alarm.
