Hanging flood sensor

Guard your home from flooding

Hanging flood sensor

We have the solution

Safe and dry

Simply mount the flat sensor onto the spot you want monitored. It reliably guards especially the areas that can be flooded by a lot of water.

Immediate flood detection

The sensory area of the flat sensor can recongize both leakage and raising water level. In those cases, you’ll be alerted by mobile notification, SMS or e-mail.

Safeguard LED diode

When the device sends a message, the LED diode will flash briefly. Thus you can check the functionality during its very activation.

Long life

The AAA battery powering the sensor can last up to 3 years, depending on the number of sent messages. ZOOCO app will alert you about low battery in time.
