Can anyone tell me how to connect a raspberry pi to a humidity sensor to a fan? The goal here is to have the fans go on once the RH goes above about 70%RH. Once the RH goes below 60% a light comes on letting me know it's time. Any info would be great thanks

Why not simply use an outlet humidity control? This one works on humidity "decrease" which is what I think you want for the light:"

(You can use relays to fire as many things as you want off one outlet)

Here's one that fires on humidity "increase" for the fans

P.S. I'm a programmer and it so happens I've been messing around with Arduino and Raspberry pi but only in my spare time which is limited lately. I could help you set this up but it's not an easy thing to program something of this nature, not so dependable without debugging. The above solution won't fail unless the sensor does.

Is the Pi specifically just to control humidity or more? If just humidity youd be further ahead simply buying a ~20$ humidity controller online IMO.
