The Efento NB-IoT recorders transmit data using the NB-IoT (Narrowband IoT) network and do not require any additional devices (router, gateway, etc.). The device is powered by two AA batteries, thanks to which the installation does not require running power and signal cables. The measurement period is configurable from 1 minute to 10 days. In addition, you can set the data transmission period to the Efento Cloud platform in order to extend the device’s operating time on the battery. The recorder allows configuration of alarm thresholds, exceeding which will cause immediate data transmission to Efento Cloud, regardless of the configured transmission period.
The recorder is also equipped with a Bluetooth Low Energy interface, which allows local data reading using a smartphone with the Efento Logger application and device configuration without connecting it to a computer or installing drivers! The device can also be configured remotely via Efento Cloud.
At the customer’s request, each Efento recorder can be delivered with a calibration certificate in accordance with ISO / IEC 17025. The test is performed in an external measurement laboratory using a laboratory thermometer calibrated with reference to the standards of the Central Office of Measures.
