I was so impressed with the dozens of inclination sensor ideas, that I'm
going to throw a question out myself:

I need a cheap, fast, and small sensor to detect when its been submerged
in (fresh) water.  I assume that this sort of thing exists for turning
on automatic bilge pumps.  We need one for our EAVE vehicle, but I was
also considering an automatic waterbowl filler for my cats...
