Bad data sent to Luftdaten project :-/

Hit a snag, even with fog where relative humidity should be 100%, it maxes out around 70-80%. Checking with supplier if it simply a faulty unit. It’s not that it’s a cheap board or anything. So far Pimoroni support have been nothing but helpful and responsive. Let’s see what the verdict is and a replacement might work better.

Even though temperature, pressure and particulate matter seem OK, I want to send it the proper relative humidity as well. Did some reading and it does turn out that sensors for RH are tricky. Looking into future versions with separate DHT22 sensor as well maybe. That way if just that sensor is spent, you can easily replace it.
