The logger is equipped with an external, waterproof probe which allows to measure the temperature in points there where the sensor cannot be placed directly. The probe is available in two variants: standard or intended for contact with food, in the form of a sharpened skewer.

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.
