Sonoff airguard 2.5

Hi

I have just got my sonoff airguard pm2.5 while the temp and humidity sensors gave reading immediately, the pm 2.5 and 10 are still showing 0 after 15 minutes. Is this normal? Have i missed something in the setup?

Thanks

Stuart

Mine is reading 0s most of the time in our office also (though I’ve occasionally seen 1s and 2s).

I guess putting it near a particulate source would be the way to check it’s working - I’ve found making a bacon sandwich is a reliable way of making the particulate levels spike at home :)

Well the dog will be happy if i am making bacon sandwiches for testing! did not expect “domestic” air to be quite so clean.

As one dog owner to another, what happens to the readings when the dog farts. :P :)

I have many weather sensor setups scattered around the house, but that’s one thing I don’t monitor. Just temp, humidity and pressure, and some light sensing for UV Index monitoring.
