LTE-M / 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 sensors transmit the data over cellular network (LTE-M and 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 / LTE-M 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
  • The device sends the data over cellular networks (NB-IoT and LTE-M) 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

Efento x IoT Creators.
Efento NB-IoT sensors have been successfully integrated with Deutsche Telekom’s platform iotcreators.com. How does it work? Set up an account at iotcreators.com -> Get a SIM card -> configure Efento sensor -> receive sensor’s messages to your server over REST.
New battery life time tool and protocol tool.
We have recently deployed a new set of tools that allow you to simulate the battery life time of Efento NB-IoT sensors depending on their settings and encode/decode protobuf messages sent by the sensors.
Efento on GitHub.
We have launched a GitHub profile, which contains code examples, tutorials on how to integrate Efento’s products into your solutions and useful tools. We will be regularly adding new tools and examples, so don’t forget to follow us!
“How warm is the water?”
This is one of the most common questions you can hear during Swedish summer. Learn how the municipality of Lerum, Sweden uses NB-IoT sensors to monitor and publish on the website current temperatures of water in the lakes.
Efento IoT Academy: BLE sensors integration.
Is it possible to integrate IoT sensors into your solution in less than 60 lines of code?
