Those water sensors/screamers are quite cheap. I recall buying 3 or 4 of them for less than $10 each. They occupy all kinds of strategic spots in the fish room. I set one off the other day just with a few drips off my hand...
The Aquatronica also has one that is stoopid overpriced...but since it is linked to the controller I'll probably buy it eventually.
