Water Sensor

Detects water and other conductive non-flammable liquids. Compatible with all ControlByWeb products with a digital input.


Prevent undetected water damage from leaking pipes and water heaters. Using no mechanical parts, the GRI Water Sensors are triggered by a moisture bridge across the sensor contacts. The GRI Water Sensors can be installed to detect a layer of water as little as 1/16 of an inch in depth.

Connected to a ControlByWeb product's digital input, once moisture is detected, it will apply 5V to the digital input, turning it 'On.' Once the digital input is on, the ControlByWeb product can send an email/text and/or trigger a relay in a local or remote location.

For more information about the GRI-2605, please see the Water Sensor Users Manual

The Water Sensor is compatible with all ControlByWeb® products that have a digital input.
