My sensor was working fine for a few months. It’s located near the area I smoke, so whenever I’m smoking it changes to red quickly. And after a few minutes (10 or so) it’d go back to green.
But for past few weeks it’s stuck at red. I disassembled it and cleaned the intake hole (which is covered with a fabric) and it worked after. However it went back to displaying red again all the time.
So my question is whether this sensor needs frequent cleaning? If so what are the alternatives?
Out of curiosity, and with no judgment intended, what is the purpose of the air quality sensor if you are actively smoking? Is it a mechanism for you to determine whether the smoking is exposing other members of the household to second-hand smoke, etc.?
I only ask because it seems to me (with no concrete research) that the smoking risk is much greater than generalized air quality risk.
I don't really have much experience with the PM1006K in the Ikea sensor but it is not untypical that PM sensors can get "stuck" and showing high concentrations.
Sometimes it helps to blow compressed air inside to push out any dust that might cover the optics but that also often does not help too much or only temporary.
