The Efento NB-IoT temperature sensor enables you to remotely monitor temperatures wherever you may be. Ideal for applications such as;

  • Medical refrigerators
  • Pharmaceutical stores
  • Museums
  • Food storage

The Efento NB-IoT temperature sensor can be easily configured via the cloud or a mobile app over BLE to report recorded measurements at your chosen intervals. This data is transmitted directly to your chosen visualisation dashboard via a cellular network. Simply insert your NB-IoT SIM card and away you go.

Users of the Efento NB-IoT temperature sensor can also configure their own alarm thresholds. If the data recorded becomes lower or exceeds your set parameters, you will be immediately alerted by your platform.

With a temperature range of -35 to 70 degrees and a battery life of up to 10 years, the Efento NB-IoT sensor offers a cost effective solution with minimal installation and maintenance.
