Hello,

How can I go about sensing water levels above .5 an inch? Im looking to avoid water levels above 0.5 inches and maybe I havnt been doing a good job with my searches, but have not found much in ways of doing this yet.

You're trying to measure the depth of a puddle?

Just position the detector 0.5" above the normal water level. A simple two probe detector will pass current when the water hits them.

Alternatively use a static pressure detector:-

Or maybe avoid a body of water somehow. Im not sure how this might be possible. If I cant figure out a system for doing this on a free roaming bot, I could just make sure that the bot is being watched and doesnt commit suicide, lol.
