Beneath the elegant white exterior, the Flood Sensor is equipped with three ultra-sensitive 24-karat gold telescopic probes that allow the sensor to precisely measure moisture and temperature levels. Using this feedback Fibaro can detect floods and take action to isolate electrical appliances and shut off water supplies to limit damage. Thanks to advanced Z-Wave technology and a battery-operated lifespan of up to five years the water-resistant sensor can operate wirelessly from remote locations for years at a time without maintenance.
