NB-IoT

Wireless thermocouple logger

The logger allows users to connect thermocouple probe and measure the temperature in the selected range. The logger is delivered without the probe and user can connect selected thermocouple probe (supported types B, E, J, K, N, R, S, T). The measurement accuracy depends on the selected probe.

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.

  • Measurement period: 1 minute – 10 days (configurable by the user)
  • The device stores 40,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
  • Battery ensures up to 5 years of maintenance-free operation
  • Use a free mobile application to configure the logger, read the data from its memory, generate reports and set alert thresholds
  • NB-IoT sensors send the data over the cellular network to Efento Cloud or any other cloud platform.

Measurement range: depends on the connected thermocouple probe. Device is delivered without probe.
