## Overview

The Floor Water Sensor is a precision liquid detection device featuring a 30ft cable and stainless steel sensor feet, designed to integrate seamlessly with home security systems and DIY electronics. Operating between 5V and 24V DC, it offers reliable, corrosion-resistant monitoring for water leaks in critical areas like water heaters, utility rooms, and sub-floors, ensuring early flood detection and peace of mind.

## Description

Level Sense LS2600 Surface Liquid Sensor connects to a control device that accepts switch-type contacts. When water or other liquids come into contact with the metal detection tab, the sensor will shorten across the liquid, providing a closed signal throughout the wire. If water is not detected, the wire will provide signal and release. This sensor is perfect for protecting computer and phone sub-floors, water reservoir, water heater plumbing, bathroom, laundry room, air conditioning, refrigerator drip pans. Use only for non-flammable liquids. Not for use with limited space. *Size: L64*W15.6*H12.7mm *Housing: ABS, White * Operating voltage: 5Vdc-12Vdc *Max voltage: 24Vdc * Maximum Operating Current: 0.5A *Temperature: -10℃~+65℃ *Colored Cable 6ft * Red wire to positive * White wire to negative (ground) * Output: NPN type Ideal for Arduio, Rasberry Pi, home electronics projects. Application Notes: There are no electronics on this device. We do not use "contact closing". Two stainless steel coated feet connect to plastic seal coated conductors, providing an environment where corrosion connects to stainless steel feet. When the unit detects water, it works as resistance from 0.6M ohm to 1.4M ohm. Water resistance is detected). It can be applied directly in some applications, but generally it is necessary to connect a circuit that senses the difference between 0V and output voltage.

## Questions & Answers

**Q: can this be used to turn off a 110V fan motor in a fan coil unit if leaking**
A: It can be used to detect the water, but would require it to be connected to a relay for it to directly switch a fan. If you look in the documentation there is a very simple circuit you can make with a solid state relay (search amazon for B00DDDFUZG). We recommend this relay because it is HORSEPOWER rated. This means that it has been tested for and is approved for use controlling motors. If you have DC power, this sensor, and the relay above, you can switch any motor load up to 3 HP, or any solenoid up to 50 amps.

**Q: Does it trigger when wet or submerged? if i use it for a wster pump, with a relay, would it stop as soon as the water level lowers or until dry?**
A: This device is not providing a “contact closure” it is providing a trickle current between the two contacts when water with some ionic content is present.
The Leak sensor behaves as an open circuit when no water is present, and behaves as a (roughly) 1.4MΩ resistor when water is present.
Water has to come in contact with both of the metal feet on the sensor to trigger a device. 
The leak sensor will continue to provide the trickle current until both feet are no longer in contact with water.

**Q: What is the upper temperature that this can handle?  can it be used to detect hot water from a water heater prv?**
A: Hello, 

The leak sensor is rated to handle temperatures up to 150F. 

I would imagine that this depends on how hot the water is that is coming from the hot water heater.

**Q: this sensor detect low resistance water ?**
A: Level Sense LS2600 Surface Liquid Sensor connects to a control device accepting an analog or digital input. 
If you are using this in home electronics projects, please take note of the following:
•	This device is not providing a “contact closure” it is providing a trickle current between the two contacts when water with some ionic content is present.
•	 The Leak sensor behaves as an open circuit when no water is present, and behaves as a (roughly) 1.4MΩ resistor when water is present. The resistance of it depends on your water.  
•	To confirm if the device is working, place the ohmmeter probes directly into water approximately 1.5” inches apart and take a reading. Then place the sensor in water and connect the ohmmeter to the red and white wires. The two readings should be similar. 
•	To get the best circuit design, put the sensor feet in water and measure the resistance with an ohmmeter.  Use this resistance in your circuit design.
•	In the unlikely event you have “non-conductive” water, it can be easily rectified by sprinkling some salt around the sensor location.  The water will absorb the salt, the salt will ionize the water, and allow it to conduct.
•	If you are using this sensor as an input to an Arduino or raspberry Pi, it is recommended to use either an Analog input, or a “PULL UP” input where the sensor is taking an input to ground.
