Wireless temperature loggers measure and transmit temperature over Bluetooth Low Energy. 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 temperature monitoring system for objects which need supervision such as medical refrigerators or pharmaceutical warehouses. The logger is equipped with an external, waterproof probe.
- Temperature: -55 to +125°C, accuracy: up to 0.5°C in the range from -10°C to +85°C and up to 2°C in the range -55 to -125°C
- Sensor is equipped with 1 m long external probe
- Measurement period: 1 minute – 10 days (configurable by the user)
- The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
- Battery ensures up to 5 years of maintenance-free operation
- 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
- Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds

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.
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.
