[0002] Atmospheric pollution detection refers to the process of determining the types and concentrations of pollutants in the atmosphere, and detecting their temporal and spatial distribution and change patterns. The purpose of atmospheric pollution detection is to identify pollutants in the atmosphere, understand their distribution and diffusion patterns, and detect the emission and control of atmospheric pollution sources. These pollutants include particulate matter, nitrogen oxides, sulfur dioxide, carbon monoxide, and ozone. Existing atmospheric pollution detection devices protect the sensors by putting a protective net on them, then use the sensors to measure the concentration of pollutants in the air, and use detectors to detect and present the pollutant concentration data. Since the protective net has mesh holes, dust will adhere to the sensors through the protective net, thereby affecting the sensor detection accuracy.
