Hello!
I'm working on 2 small projects and wanted to see if people had any thoughts.
One of them is a temperature/humidity sensor, plugged into a Pi which is in turn attached to a heating element. The idea is to maintain a constant(ish) temperature/humidity in an enclosed area (I want to make an environment for growing Oyster Mushrooms). I've ordered this relay:

A potential problem I've thought of is how humidity and ambient temperature might not always line up so I might eventually need two heating elements, one in water and one in the air.
Any suggestions? How would you guys do it?
