If it's a standard PM sensor, those usually have a high temperature correlation that needs to be compensated for, and turning on the heat in the morning would likely produce a false positive with only naive signal processing.

I have laser PM sensors indoors and outdoors. Every morning my indoor one goes nuts. I have found that it's due to my SO spraying hair products.
