What you're looking for is called a "waterbug" It has a pair of dry contacts that close a circuit when it gets wet. you could set up an arduino, or just wire it to a buzzer. On 8/18/12, Eric Martin <eric.joshua.martin@gmail.com> wrote:
Hey all,
I had a close call with my hot water heater this afternoon. I heard on odd noise in the pipes and it turned out that my hot water heater was dumping water out of the overflow valve. Luckily, I found it quick enough, and I'm pretty sure I got it handled for < $150. There's a 1 Gal bucket under the overflow valve, and if I had a water level detector emailing me that water is in the bucket, I could have caught this earlier.
I was looking at buying an Arduino and setting up a simple circuit. I know a few people have played with Arduinos, any suggestions on which one to get and how to go about it? I don't need to know how much water is in the bucket, I was thinking about a float type device or even two wires that trip a relay. I just want a heads up that water is in the bucket so I can stop before my basement floods.
Thanks in advance, -- Eric Martin
