Just a thought and apologies if a silly question, but is this unit
simply measuring the indoor RH?

Thanks Bob and no, it's not a silly question. I was originally interested in
the RH in the garage as that's where my pet project will be undertaken.
However, for the purposes of the comparison, I've been leaving it outside.
Having said that, it's situated close to the house but it is sheltered so
that it can't be rained on.
