TOPIC: AirBeam2 - zero or close to zero PM (1, 2.5 and 10) readings

Hi al,
I just purchased an AirBeam2 sensor. The first time I tried it there were some low PM readings but they were there. However, all I get now are readings equal or very close to zero (1-2) for PM1, PM2.5 and PM10. Temperature and RH seem to be OK. Does anyone know how to solve this issue?

I saw this question previously and someone saying AirBeam only reads PM2.5. AirBeam 2 does as far as the website says "AirBeam2 (...) can measure PM1 and PM10 in addition to PM2.5".

Sounds like the air you're measuring doesn't contain much particle pollution. If you'd like to test the response of the AirBeam2 to particulate matter burn some paper.
Thanks admin, I think the issue as OK now!
