Bluetooth Low Energy

I / O logger

Wireless I/O sensors monitor the state of a machine, door or any other object that changes its state. Sensor can detect the state of an alarm output of a device connected to it.

You can use a free mobile application to configure the device and read the data from its memory. If you add Efento Gateway, you can build a remote monitoring system for objects which need  supervision such as medical refrigerators, warehouse doors, or windows.

  • Battery ensures up to 5 years of maintenance-free operation
  • Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
  • Add Efento Gateway and Efento Cloud to build a real time monitoring system.  The maximum distance between the sensor and the Gateway is 100 m in the open space and 20 – 30 m in the buildings
  • The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten

Wireless I/O logger - Bluetooth Low Energy

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 5 years on battery. You can forget about changing the battery frequently or troublesome battery 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.
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.
Data security
Data transmitted wirelessly can be encrypted. Thanks to that, unauthorized persons cannot hijack the communication between sensors and other devices. Efento sensors' software can be updated over the air, which will allow you to easily install any security patch that is released.
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.
