Hi, as wasn’t successful @ Discord, I try it here as I am really stuck.
My enviroplus board is mounted piggy back style on Raspi Zero, th case ist like this one
My BMS280 shows much lower temp (°C) reading than references
BMS280 Reference1 Reference 2
1.75 6.1 6.1
-1.57 4.1 4.1
-2.12 3.9 4.0
-4.17 3.0 2.8
On the other hand the PM reading “seems” far to high. It looks like fog is terribly increasing PM values, which sound logical as fog can deflect/reflect laser. I read an article this is compensated in professional equipment !? Any chance to increase accuracy with the enviroplus?
Any help appreciated, as the current setup isn’t worth the electrical power spent to operate it.
