Dust Sensor DSM501A / Sensor debu for arduino

Overview



The dust sensor module DSM501A is low cost,compact size for a particle density sensor.



Quantitative particle measurement with the principle of particle counter.

FIne particle of which diameters are bigger than one micron could be detected with high sensitivity.

Inside heater realizes the self-air taking.

One control contact and two output contacts.
