NB-IoT

Wireless illuminance logger

Wireless illuminance logger is a lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and strong IR rejection of the device enables it to accurately meter the intensity of light as seen by the human eye regardless of light source.

Efento NB-IoT loggers 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.

You can use a free mobile application to configure the device and read the data from its memory. 

  • Measurements: 0.01 lux to 83 000 lux
  • 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
