Air Particle Counter Sensors use Lasers to Detect ...

Air Particle Counter Sensors use Lasers to Detect March 18, 2021. Particulate matter like dust, pollen, mold, smoke, and even metals are in the air we breathe. Too much particulate matter in the air lessens the ability of the lungs to take in oxygen. With repeated exposure, this leads to difficulty breathing, lung disease and even death.
