Abstract

The invention provides a PM2.5 detecting and broadcasting apparatus, which is cooperatively used with a mouth mask. Hanging ropes of the mouth mask are hung on a hook, so the PM2.5 detecting and broadcasting apparatus is fixed at the back side of a head; air in an external environment enters an accommodating chamber via through holes; a light source and a camera are used for measuring the concentration of PM2.5 in the air in the accommodating chamber; and the measured concentration value of PM2.5 in the air is displayed via a liquid crystal screen. The PM2.5 detecting and broadcasting apparatus is convenient to use; and the value of PM2.5 can be broadcasted for a user in time in virtue of the liquid crystal screen, so a user can conveniently learn about current air quality.

Description

technical field [0001] The invention relates to a PM2.5 detection and broadcast device, which belongs to the technical field of environmental detection equipment. Background technique [0002] PM2.5 refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It 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 health and atmospheric environmental quality. [0003] Therefore...
