I have 2 of the TH02-based Grove Temperature & Humidity sensors (SKU: 101020074). Both of them return inaccurate readings: the temperature is about 3C too low, and the humidity is about 20% too high. The readings aren’t random - they rise and fall correctly, but are consistently off the correct value.
I’m using the sample Arduino code from the Wiki.
Is anyone else seeing this behaviour? Any ideas what might be causing it?
