NB-IoT

Wireless high temperature logger

Efento wireless high temperature NB-IoT sensors are designed to monitor the operation of devices requiring constant high temperatures, e.g. bakery ovens, industrial drying ovens. The loggers are equipped with a 1m probe with a Pt1000 sensor, which can be safely placed in a place with high temperature.

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: -70 to +450°C, accuracy: up to 0.3°C in 0°C and 1.8°C in +300°C
  • 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
