Just one caution with the saucers for the radiation shield. I notice that they have a bit of a turn up at the edge.
If it is able to be rained on, the lip will hold a small amount of rain and that can affect the humidity reading until it evaporates. Better if possible to have ones that the rain can just run off.

You are right. That's why all the dishes have small holes near the border. It's difficult to see them on the image, unless you know they are there.
