[0002] Air monitoring refers to the fixed-point, continuous or timed sampling and measurement of pollutants existing in the air. In order to monitor the air, several air monitoring points are generally set up in a city, and automatic monitoring instruments are installed for continuous automatic monitoring. The items of air monitoring mainly include sulfur dioxide, nitrogen monoxide, hydrocarbons, and floating dust, etc. Air monitoring is the basis for air quality control and reasonable evaluation of air quality.

Ambient gas is transmitted to the inside of the detector through the intake mesh holes in the outer shell of the host and the intake mesh holes in the outer shell of the detector, and is finally discharged through the exhaust mesh hole on the side surface of the detector.

[0057] When the ambient gas passes through the detector, the volatile matter sensor, PM2.5 sensor, PM10 sensor and formaldehyde sensor inside the detector will identify and analyze the concentrations of corresponding substances in the air.

[0058] The concentration of the detected substance analyzed by the detector is converted into an electrical signal and transmitted to the signal processor of the Internet of Things terminal.
