[0032] When using the odor gas monitoring device, if Figure 1 , Figure 2 and Figure 4 As shown, the upper end of the shell 1 is fixedly connected with a top plate 2, and the top plate 2 is fixedly installed on an external bracket by bolts. At the same time, the inside of the shell 1 is fixedly connected with a mounting column 9, and the lower end of the mounting column 9 is installed with an odor monitoring sensor 10. The odor monitoring sensor 10 is placed in the shell 1, and the odor enters the shell 1. The odor monitoring sensor 10 can monitor the odor and odor in the environment. In the actual monitoring process, when encountering rainy weather, there is water mist and moisture in the air. The left and right ends of the shell 1 are fitted with a filter 4, and the pore size of the filter 4 contains desiccant powder. The gas enters the shell 1 through the filter 4, and the gas can be dried to prevent the water mist and moisture in the gas from affecting the monitoring result of the odor monitoring sensor 10, thereby ensuring the precision and accuracy of odor monitoring, and the practicability is high.
