Floor Water Sensor Flood Detection Review

Normal open, closes when there is little water. I used it as an external input on my pool controller to stop the pumps when water is detected where it shouldn't be.

Works great with Waterbug WB200 which uses unattended sensors like these. I connected them in parallel and they work great. I wish the cable was a few feet longer, but it ended up working for my setup; I just had to move the WB200 a bit.

I built a water shut off system using a flood sensor, a 120-24V power supply, a 24V solid state relay and a 24V normally open solenoid. The sensor is in series with the power supply and the SSR and activates the SSR when water completes the circuit then the SSR sends power to the Selonoid and BAM, done!

I used this to create my own "leak detector" for the occasional leak in our garage ceiling. I built a circuit similar to the example provided and it works great! It is a well built unit and I will definitely be buying it again for all my leak detection needs. Comes with pre-stripped and tinned wires which was a nice touch.

This is a good water sensor to connect to the controller. I used it with an Arduino to detect a drain backed up when my washing machine drains. I used a relay and was able to pause the washing machine until the drain water stopped. The sensor detects quickly. I agree that it would be nice if the chord was longer, but lengthening it is easy enough. The included app notes are nice. You'll have to play with the value of the pull-up resistor you add to work with the standard TTL input pin.

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.

Just received this item. Use it to automatically add water to the pool. I have a 12-bit ADC connected to it. A 10 MΩ resistor divider is required. Several tests were performed, including being completely submerged in water for several hours and then being completely removed from the water. Works perfectly. As the device dries, the voltage approaches 0V. Will go into production shortly. Update: Unfortunately, after one season, pool water chemistry caused the wires to erode. As a result, my use…

pens are flimsy tabs in a $13 plastic case. You can use regular barbed wire and get the same functionality you probably already have in your home. The easiest way is a DC solid state relay. Pure water (distilled, reverse osmosis, and what drips from an AC unit) will not conduct electricity and will not activate your relay. To solve this problem, sprinkle the contacts with some rock salt (table salt also works). When water forms puddles, it absorbs salt and becomes conductive. Rock salt (ice…
