IoT Products

NB-IoT temperature sensors transmit data wirelessly to Efento Cloud using the backbone network and Narrowband-IoT communication technology. Thanks to this, to send measurements from the sensor you do not need any additional devices! Efento Cloud enables, among others measurements recording, notifications about exceeding safe thresholds and generating automatic reports. The sensors are also equipped with the Bluetooth Low Energy interface and enable local data readout and configuration using a smartphone with the Efento Logger application. The devices are powered by batteries that ensure their maintenance-free operation for a period of at least two years. The sensor logs 65,000 temperature measurements in its memory.
