Leak sensors

Leak sensors (flooding)

— household sensors that react to the appearance of moisture on the floor or other surfaces.

Such a sensor is installed right in the place of possible flooding, and a pair (or several pairs) of special contacts are used for detection: even a small amount of water between the terminals closes them and leads to operation. Contacts can be placed both on the sensor body itself and on a remote unit connected to it with a wire. Some of these devices also have a temperature sensor function.
