Dust sensing kit, for particulate matter concentration monitoring.
Particulate matter concentration is the sum of all solid and liquid particles suspended in air many of which are hazardous. This complex mixture includes both organic and inorganic particles, such as dust, pollen, soot, smoke, and liquid droplets. These particles vary greatly in size, composition, and origin. Particle pollution includes “inhalable coarse particles”, with diameters larger than 2.5 micrometers and smaller than 10 micrometers and “fine particles”, with diameters that are 2.5 micrometers and smaller.
Those particles damage the environment and are directly related with serious human health problems. Prolonged exposure to coarse particles, called PM10, can irritate eyes, nose or throat, and provokes breathing diseases. Fine particles, PM2.5, can get into the deep parts of your lungs, even end up in your blood stream.
