My AM2315 is sitting under my weather box on top of a shingled roof. It never has a fighting chance to do correct readings, with all the heat transfer from the box (even though the box is shielded by the solar panel) and from the roof.
I was wondering if adding a second sensor in a slightly shadier location (say, behind the box rather than under it) would give me an option to do some differential trickery with the temperature reading. Like they do with multiple sensors on airplanes that need to agree on their readings.
let's say the front sensor A says 105F, and the back sensor B says 95F. The real temperature T is 85F.
So I could say T = B - (A - B) or T = 2B-A
This would work at night too when both sensors agree again. Obviously i'd need to calibrate the in-between values and factors.
