I have seen lots of posts and advice over Temperature accuracy, I have my sensehat on a ribbon cable extension....
I have some reason to suspect that my humidity reading is too high. Around 15%. However I cannot prove it. I have cheap humidity instruments to compare the values, but they can't agree, either.
It is working, i.e. when our wonderful country does its thing of torrential downpours, the humidity increases, I just think it is too high for indoors. getting paranoid about damp....whatever happened to warm dry summers?
Can anyone suggest a cheap / accurate way of checking and calibrating a humidity instrument?
