Hi,

I have built my Air Quality Monitor and am testing it  sitting it outside on a bucket. There is no enclosure for it yet.

CO2 reading seems a little high at about 600 -700 ppm, think it should be about 400. Is this a reasonable measurement?
Is the sensor reading ok? At first boot, it reads about 1200 - 1300, and then drops to 600 - 700.

The plantower pms7003 is working, PM readings are very low on this with AQI of about 2 or 3 max. Either the sensor is not working well or I have very clean air! I live in rural Ireland, about 1km to nearest road, and we had a lot of wind and rain yesterday, so I think I would expect them to be low at the moment.

Any comments are welcome, not sure what my ballpark readings should be.

Thanks,
Heeby
