Air Quality Sensors in Trondheim Kommune

The air quality sensors are part of a project to augment the existing air quality sensors with cheaper sensors in larger numbers. The new sensors uses the Span service to transmit data up to a backend that processes and visualizes the data. These sensors are an evolved version of the earlier LoRaWAN sensors but with NB-IoT connectivity through SARA N modules.

Several scientific papers have been written about the project:
