A wireless sensor network composed of multiple exhaust gas detection nodes and central processing modules based on STM32 was developed to complete the multi-point real-time monitoring of industrial exhaust gas.The hardware circuit and software program of the detection node and the central processing module were designed,the hardware circuit of detection node was developed with STM32,gas sensor and ZigBee module,the hardware circuit of central processing module was developed with STM32,GPRS module and ZigBee module,and the upper computer interface of the system was written with PYQT.STM32 collected and packaged data,ZigBee module realized multi-point transparent transmission of data,and GPRS module completed remote transmission of data and sending of early warning information.The experimental results show that the system can accurately monitor industrial waste gas,record the detection results in real time,and realize the short message early warning function.
