LTE-M / NB-IoT

Wireless temperature logger

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.

  • 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
  • The device sends the data over cellular networks (NB-IoT and LTE-M) to Efento Cloud or any other cloud platform.
  • Batteries ensure up to 10 years of maintenance free operation
  • Measurement period: 1 minute – 10 days (configurable by the user)
  • User configurable alarm thresholds. If any of the thresholds is exceeded, sensor will send the data to the platform immediately
  • The device stores 60,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
  • Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy
