My house has a large air volume, the 2nd floor is half as big as the first, so half the first floor has 20 foot ceilings. I don't monitor NO2, but do monitor PM2.5 and CO2. I see no difference in PM2.5, but do see my baseline of 550-650 CO2 bump to 1500 with significant gas stove usage. The CO2 spreads quickly, my basement and bedroom sensors follow the 1st floor pretty quickly.

If people want a air quality sensor that can upload data to the cloud (by default) or your local graphana, including source for an exporter, I'd check out airthings, their units are basically turnkey and can, but don't require) use a cloud.

I'm definitely shopping for an induction stove soon.
