[0002] Environmental monitoring refers to the monitoring and evaluation of various indicators in the environment in order to understand the quality and changes of the environment. The purpose of environmental monitoring is to protect the environment, prevent environmental pollution, control pollutant emissions, and evaluate environmental impacts. Environmental monitoring can include monitoring of the atmosphere, water, soil, noise, etc.

[0003] Dust concentration detection is one of the important contents of environmental monitoring. It is used to evaluate and monitor the degree of dust pollution in the air. Dust is solid particles suspended in the air, including fine particles PM2.5, with a diameter less than or equal to 2.5 microns and inhalable particles PM10, with a diameter less than or equal to 10 microns. Dust concentration detection usually uses a particle concentration monitoring instrument, but some existing dust concentration detection devices will expose the detection head to the outside at all times during actual use, so as to contact with the outside air to make the detection effect more accurate. However, this method will make the detection device head vulnerable to damage and will also be more likely to adhere to more dust, which will have a certain impact on the detection results.
