NB-IoT
Wireless water rope logger
Wireless water rope 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. The sensors are equipped with a detection cable that allows you to designate a zone monitored for leakage.
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 the presence of a conductive liquid at any point along the entire length of the probe
- Sensor sends the information to the cloud as soon as it detects water leakage
- Probe length: 3m (different lengths available on request)
- Battery ensures up to 5 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
Key features
Efento Cloud
Together with Efento Cloud, the sensors enable constant monitoring, alerting about exceeding safe limits, generating reports and analyzes.
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.
Integration
Standard communication protocols allow integration with any cloud platform or mobile application.
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.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.

Case studies
Implementation of Efento Cloud temperature and humidity monitoring system
Hospital pharmacy uses Efento Cloud for monitoring temperature and humidity in refrigerators and rooms where medical products are stored.
Archives of the Jagiellonian University
The Archives of the Jagiellonian University are one of the oldest and largest university archives in the world. Efento loggers measure temperature and humidity, ensuring control over the proper storage conditions of exhibits.
Monitoring of Physical Conditions in Warehouse and production halls
Appropriate climatic conditions for storing products must be maintained in warehouses. Implementation of the Efento wireless monitoring system has allowed for constant supervision over the conditions in buildings and industrial halls.
Implementation of the Efento Cloud temperature monitoring system
In accordance with applicable regulations, hospitals require constant monitoring of parameters such as temperature in medical refrigerators.
Using the Efento solution allows to inform hospital staff via SMS or email in the event of an emergency (e.g. sudden increase or decrease in temperature in a vaccine fridge).
