If you're going home-brew, detecting water could be as simple a couple
of paperclips on a piece of plastic feeding a suitable amplifier.
For moisture sensors, get a bit of veroboard, link alternate tracks,
attach wires then add a couple of drips of saturated salt solution and
allow it to crystallise. Not sure how good that is for your application
(suspect it would need replacing regularly), but it's so fiendishly
simple that I thought it deserved a mention...
