Water leak sensors are used in places where uncontrolled water loss can cause major damage, such as archives, museums, server rooms, warehouses, and laboratories. This sensor is ideal for detecting leaks at heating installations, air conditioning systems, dishwashers, washing machines, pumps, refrigerators, and freezers.

With the free mobile app you configure the device and read out all data from the internal memory. Add an Efento Gateway and easily build a complete remote monitoring system.
