I built a PM2.5 and PM10 monitoring "box" for Home Assistant when we got our log-stove installed.

The goal was to know how bad the air quality would be in our living room / home.

Having used it for several weeks, now I've learned a couple of things;

The air quality _in_ the house is usually _much_ better than it is outside, for example, I measure an average of 1-2ug/m3 inside, but if I take it outside or open the window it can rise to 20-30ug/m3, we live on a fairly busy road. I looked into the UK air quality guidelines and the advice is literally to "close your windows".

Second, the log stove has no effect on the (PM) air quality in the living room when burning properly, however, opening the door to refuel, or not lighting it to a proper burn can cause the levels to shoot up to 70ug/m3 or as high as 200ug/m3 if you let a lot of smoke out while dicking around with the fire, this has a pretty slow fall-off and usually takes hours to drop back to "normal".

I want a CO2 monitor next to check CO2 levels too.
