Abstract

The invention discloses a device and a method for measuring PM2.5 concentration based on a nonwoven fabric resistance method. The measuring device comprises a box body, a nonwoven fabric circuit measuring unit which is arranged inside the box body, a nozzle which is arranged inside the box body, and a liquid storing device and an air storing device which are connected with the nozzle, wherein valves are arranged between the nozzles and the liquid storing device as well as the air storing device; the nonwoven fabric circuit measuring unit comprises a nonwoven fabric which is arranged below the nozzle and a power source, a switch and a current measuring unit which are electrically connected with the nonwoven fabric. The device for measuring the PM2.5 concentration is simple in structure, can be widely applied to detection in daily life and can be used for enabling people to know the air quality at any time and enhance personal protection so as to improve the air quality more proactively.

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...
