Wireless water leak logger
SKU: 5906660327677
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.
KEY FEATURES
➔ Long battery life
Loggers have been designed to work for up to 10 years on batteries. You do not have
to remember about changing the batteries frequently or troublesome batteries
charging.
➔ Lower costs
Choosing wireless sensors and a cloud platform reduces the installation and
maintenance costs.
➔ Wide range of sensors
Efento sensors can measure various physical and chemical values. If you decide on one
sensor today, you can expand your sensors fleet to another types anytime you want.
➔ Any cloud platform
Standard communication protocols allow integration with any cloud platform or mobile
application. Logger works with Efento Cloud out of the box.
➔ Easy set up
All you need to set up a logger is a smartphone with a free mobile application. The
whole configuration takes no more than 15 minutes.
➔ Remote configuration and updates
All logger settings can be configured remotely from the cloud platform. Moreover,
logger’s software can be updated remotely.

ADDITIONAL INFORMATION
Edge analytics
Devices analyse the data and send it to cloud platform when needed. This allows to decrease the
number of cellular transmissions and increase the battery lifetime. There are several types of
analyses that can be performed by the sensor: from a simple comparison of the measured value
to the threshold to more complex mathematical operations.
Software over the air update (SOTA)
The sensors are equipped with over the air software update mechanism, thanks to which, your
fleet of sensors will always have the latest version of software. Moreover, SOTA is based on delta
mechanism and only the difference between the current and the new version of the software is
sent to the device. This saves both the battery and data transfer.
Full remote configuration
All the settings of the NB-IoT sensors can be changed remotely in a secure way. This allows you to
easily reconfigure thousands of the deployed devices, no matter how far they are located.
Integration
We believe that the Internet of Things is about integrating data sources, analysing the data and
drawing conclusions based on it. If you want to integrate Efento loggers with your software, cloud
platform or mobile application, we will provide you with the necessary documentation, libraries,
SDKs and we will gladly assist you.
Sensor’s passport
Sensor’s passport documents the entire lifecycle of a device. By accessing the data on Efento
Cloud platform, the user can check all information about the sensor: date of sale, warranty status,
date of calibration, information on all service activities. In addition, the user can download all
documents regarding the device – a duplicate of calibration certificate or service protocols.
