Water leak sensors are used in places where uncontrolled leakage can cause large damage, e.g. in archives, museums, server rooms, warehouses, laboratories. They are ideal for monitoring leakage from heating devices, air conditioning systems, dishwashers, washing machines, pumps and refrigerators or freezers.

Efento NB-IoT sensors transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.
