The staff carry this utility model to the position where gas monitoring is to be carried out. After arriving at the destination, the staff use screws to insert into the fixing holes to fix the bottom plate at the position to be monitored. After the installation of this utility model is completed, the staff adjust the position of the top box according to the height position of the air to be monitored. The specific adjustment operation is that the staff raise the inner rod. After the inner rod is raised to the height that needs to be adjusted, the staff insert the bolt into the inside of the first jack and the second jack to limit and fix the top box at the existing height position. The staff externally power - supply this utility model. After external power - supply, the wireless device in this utility model can transmit the monitoring data to the terminal device in real - time for the staff to know. The staff can also perform setting operations such as timing on the operation of this utility model through the terminal device. The air cylinder installed on one side inside the first cavity has its internal fan running, sucking the external gas into the inside of the first cavity through the first air inlet. The gas entering the first cavity will be monitored by the monitor body to obtain data, and the monitored gas will be discharged through the air outlet. When the previously set time arrives, the fan in the collection cover will run, and the external gas will enter the inside of the shunt pipe through the second air inlet.
