Fibaro flood sensor with the most sophisticated design is the finest of its kind. The battery-powered device is Z-wave and Z-wave+ compatible. Z-wave is the most popular wireless communication protocol used in home automation. The device has a built-in temperature sensor that monitors the temperature of the floor where it is placed. It is designed to be either placed on the floor or wall-mounted.

The device has a built-in LED and sound alarm to indicate flood threats. Whenever a threat happens, the sensor detects it sends out Z-wave control signals to the alarm system and the Z-wave devices by opening an NC contact.

Installations can be done maintenance-free and without professional skills. Like all other Fibaro smart devices, the design is inspired by nature and this time it looks like a water drop.

The philosophy and thought behind the shape are simple- In the beginning, there was only a water drop and the flawless shape of a water drop. The enclosure is made of high-quality and glossy plastic in white color and is secured from being opened, turned off, or destroyed. Any such attempts will be notified instantly.

The most versatile flood sensor from Fibaro detects any attempt to move it by sensing the tilt or movement over 15 degrees. The gold telescopic probes of the device allow it to work smoothly on uneven surfaces. The input terminal of the device helps it to be connected to the external probe so that the sensor can be installed in any location.

The output terminal connects it to an alarm system. Any sort of wired alarm system available in the market can be integrated into the device. The alarm notification can be sent through wired or wireless communication modes.

The Fibaro flood sensor will respond to the threat of flooding by closing the water supply if a solenoid valve coupled with a Fibaro relay switch unit is installed in your hydraulic system. The device can be operated in the toughest conditions as the operating temperature range is between -10°C and 95°C. Fast and slow floods can be detected alike and the device is difficult to be submerged. All these unique features ensure great safety for your home.
