Libelium
Air Quality Station
Indicative pollution monitoring for cities, calibrated against reference stations with machine learning managed from Libelium Cloud.
- SO2, O3, NO, NO2, CO
- PM1, PM2.5, PM10
- LTE (4G)
- Mains powered

Overview
The Air Quality Station is an indicative air quality monitoring station designed to complement high-cost reference stations in cities and around industrial sites. It combines electrochemical gas sensors, optical particulate counters, a weather station and a noise sensor, and uses machine learning calibration managed from Libelium Cloud. It connects over LTE (4G) and runs on mains power.
Built for
- Dense urban air quality networks
- Industrial perimeter monitoring
- Supplementing reference stations
- Urban noise monitoring
Key features
Gas and particulate sensing
Measures SO2, O3, NO, NO2 and CO plus PM1, PM2.5 and PM10.
Weather and noise
Includes wind and compass, precipitation, temperature, humidity, pressure, solar radiation and a Class 2 sound meter (IEC 61672).
Reference co-location calibration
The station is deployed next to a reference station for one month, then AI models are trained in the Libelium Cloud Model Factory.
Golden node calibration
For large projects, further stations can be calibrated against a node already calibrated against a reference station.
Universal models
Projects without access to a reference station can use Libelium's generic AI model built from co-location data.
Remote management
OTA programming, parameter configuration and reboot over the LTE network from Libelium Cloud.
