Thanks for you input, much appreciated. Was indeed thinking about a fan as well, but wanted to keep it all passive :-/ Do you have a part list and designs shared actually?
At the moment I am running it next to my NetAtmo indoor station and comparing the values. I have rewrote some things to compensate for humidity. That simply seems to register too low, however long a cable you use. Thing with humidity sensors is they degrade over time and have a relatively short lifespan. Once it’s enough to my liking, I need to look for a casing.
Any idea if Pimoroni is looking into this design wise as well for a next itteration of the sensor board?
