How to Build a Particulate Matter Detector for Air Quality ...

· An internal laser light source illuminates particles as they are transported, via the air inlet and the exhaust fan, through the detection chamber. Particles obscure the light and change the electrical activity of an internal photodiode. That activity is analyzed and converted to a particle concentration, which can be transmitted through the serial interface. Sensor Interface and Commands. The ...
