Floor Water Sensor for Flood and Leak Detection (6 ft)

2 wire easy install. Tested out fine.Buy with confidence

I had previously asked a question through Amazon on how far I could extend the wires on this unit. The response I got was that it had only been tested up to 30 feet. I can confirm the product works fine at least up to the 50 feet of wire I used to extend it (I wasn't able to respond to my own question). I used typical CAT5e wire that I had around, bundling 4 of the 8 strands together to create 2 heavier gauge wires. Works just fine when paired with an Arduino using a digital PULL_UP pin and the onboard ground connection.

I wanted to know when the drip pan in my attic air conditioner unit had water in it. I wired this sensor into the NO/NC contacts on an Avigilon IP security camera. When the pan fills with water, the sensor activated the input on the camera and sends a alert to my smartphone and sounds a buzzer I mounted to the wall. Great sensor for the price!

I was trying to hook it up to my home a/c system, but it is a "Normal Open" switch and I need it to be "Normal Closed"

I hooked 3 of these sensors up to my Lorex nvr alarm inputs. When my basement floods, I’m sent notifications. I installed an 8v dc power supply directly in line with the sensor circuit. So basically when the two prongs are in contact with water, the circuit is closed and sends that 8v current into the alarm input. Works perfectly
