NB-IoT

Wireless carbon dioxide (CO2) logger

Efento NB-IoT wireless carbon dioxide (CO2) logger measures gas concentration and transmit its values over a cellular network (Narrowband IoT). On top of the gas concentration, the logger also measures temperature, humidity and barometric pressure. Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT CO2 sensors can be integrated with any cloud platform.

  • CO2: 400 ppm – 5000 ppm, accuracy ±(40 ppm + 5 % of reading)
  • Temperature: -35 to +70°C, accuracy: up to 0.4°C in the range from -20°C to +70°C and up to 0.5°C in the range -35 to -20°C
  • Humidity: 0 to 100% RH, accuracy 4% in the range of 0 to 80% and 7% in the range of 81 to 99%
  • Pressure: 300 to 1100 hPa, absolute accuracy +/- 3 hPa at 0 to + 65°C, relative +/- 0.12 hPa at 0 to + 65°C, p = 800 - 900 hPa
  • Batteries ensure up to 10 years of maintenance free operation
  • NB-IoT sensors send the data over the cellular network to Efento Cloud or any other cloud platform.
  • 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
  • Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy

Newsletter (January)

NB-IoT CO2 sensor released!
We recently released the NB-IoT CO2 sensor. It may be used to monitor the CO2 levels (400 ppm – 5000 ppm) in office spaces to prevent spreading of COVID-19 disease.
NB-IoT motion / presence sensor released!
Allows to detect motion (like regular PIR sensor used in alarm systems) or room occupancy (conference rooms, office spaces, etc.). User can configure the device to detect every single movement or set the number of movements in a time period required to detect the room occupancy
Preserving stained glass windows for the next generations
Discover how Efento NB-IoT sensors are used by the conservation team of St. Marien church in Lübeck (Germany) to monitor the environmental conditions.
Efento CoAP loader update
Efento CoAP loader provides an easy and quick way to integrate Efento NB-IoT sensors into custom solutions. We recently updated it to support all sensor types and all their features
IoT connectivity from space?
Rakuten and University of Tokyo exploring low Earth orbit satellites for IoT coverage. The joint R&D project will span the next four years and involve the creation of a satellite network to connect NB-IoT and LTE devices.
