Abstract

The invention discloses a PM2.5 concentration measuring device and method based on a non-woven fabric resistance method. A connected liquid storage device and a gas storage device, a valve is arranged between the nozzle, the liquid storage device and the gas storage device, and the non-woven fabric circuit measurement unit includes a non-woven fabric located below the nozzle, and a non-woven fabric electrically Connected power supply, switch, and current measurement unit. The PM2.5 concentration measuring device of the present invention has low cost and simple structure, and can be widely used in the detection of daily life, allowing people to know the air quality at any time, improving personal protection, so as to more actively improve the air quality.

Description

technical field [0001] The invention relates to the technical field of PM2.5 concentration measurement, in particular to a PM2.5 concentration measurement device and method based on non-woven fabric resistance method. Background technique [0002] PM2.5 (fine particulate matter) refers to particulate matter with a diameter less than or equal to 2.5 microns in the ambient air. PM2.5 can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, large area, strong activity, and is easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact on human healt...
