NB-IoT

Wireless water leak logger

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.

  • Detects presence of a conductive liquid at the level at which the probe is mounted
  • Sensor sends the information to the cloud as soon as it detects water leakage
  • Probe length: 3m (different lengths available on request)
  • Batteries ensure up to 10 years of maintenance free operation
  • NB-IoT sensors send the data over the cellular network to Efento Cloud or any other cloud platform.
  • Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy
  • The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
