I've got this crazy idea for a project of adding ultraviolet LEDs to a shower curtain that turns off after humidity levels drop. I'd like it small and extremely low power so I'm wondering what kind of arduino or micro-board would work well for that and are there humidity sensors that work with it?

First thought: adafruit tinsy?

Sensors: arduino can do it, tinsy can to

This sensor would do the trick. A quick google search shows that there is an arduino library for it.

Kevin Darrah? is doing a series on YouTube about ultra low-power Arduinos. I'd guess you could probably run something like this off batteries for a couple months if done right.
