The problem is that i have different values than yours, so this seems to be all over the place. I’ll try to calibrate my two sensors in the real conditions expected, starting this weekend.
I will keep you posted.
I have to add that this lack of support from Seed Studio on this simple matter is making me consider the use of the Grove ecosystem altogether because it is supposed to be a solution to simplify integration. But in the end, without support and with this kind of errors it is useless as an ecosystem.
