Review on Floor Water Sensor Flood Detection by Zachary Caldwell

I previously asked a question about Revain about how far I can extend the cables on this unit. The answer I got was that it was only tested up to 30 feet. I can confirm the product works well up to at least 50 feet of wire I extended it with (I couldn't answer my own question). I used the typical CAT5e wire I had and tied 4 of the 8 strands together to create 2 larger wires. Works well with an Arduino with the PULL_UP digital pin and built in ground.
