You and me both!
Sadly, I don't think a tutorial exists. I've been doing a lot of experimenting on sensors lately, and when I'm 100% positive I have the way it works figured out I was going to post it here and share it with anyone, but I'm not aware of anyone having done that before.
Is there something in particular you're trying to do? If you can narrow it down a bit, maybe I can give you some pointers.
