Kietųjų dalelių, dulkių jutiklis DSM501A

The dust sensor module DSM501 is a compact sized particle density sensor.

Quantitative particle density measurement with the principle of particle counter.

Fine particles of bigger than one micron could be detected with high sensitivity.

Inside heater induces air inflow to the module.

One control contact and two output contacts
