Dust Sensor

Recommended Posts

Is dust sensor detecting any standarized dust particle size, like PM10 or PM2.5

Can it be used for the smog detection?  The spec of the sensor is not saying that?

The Dust Detector Bricklet can not be used to determine PM10 or PM2.5. This would require that it can distinguish between many small particles and one big particle, which it can not.

 

E.g. pollen (from flowers) would not be registered in PM2.5, since the pollen particles are quite big. But they would register in the Dust Detector Bricklet.

I ordered the sensor with the purpose of seeing if traffic pollution can be detected. I don't actually care how the pollution is classed (PMxxx whatever). I'm only interested in seeing a change in value when the traffic is known to be sending us polluted air in our direction.

 

Will report back here once I've been able to test the sensor (waiting on delivery).

Looking forward to your findings. I would prefer my smart home to be a regular AQI station, but maybe it wil give some relevant data anyway.
