Are there any bright sparks on board who could give me some pointers on how to make a moisture detection system ?
Basically, I have a alloy camera housing and would like to build a circuit that could detect a slight leak. I was thinking of something small, lithium button cell powered, with a red LED that I could fit just inside the window.
I guess a simple couple of wires at the bottom of the housing that would make a circuit if bridged by water would work but I was kind of hoping for something a bit more clever, maybe resistance based.
