particulate matter

For outdoor particulate matters

PAS-OUT-01 is an optically designed industrial-grade, digital laser sensor

to measure particulate matter. It comes with a built-in laser and photoelectric receiving module.

Different than its contemporaries, PAS-OUT-01 is calibrated for PM10 and PM2.5 separately. It works on the principle of

90° light scattering. The light that strikes the aperture of the mirror at 90° is reflected towards the sensor.

The photodiode registers pulse for as long as the light is reflected. The electrical signal thus received is converted

into concentration of particulate matter by specific algorithms.
