Air Quality Station
Cities are demanding reference Air Quality Stations that have high costs to monitor key pollution parameters. Libelium solves this by providing smarter, smaller and more affordable Air Quality Stations that collects and analyses data through Libelium Cloud using Artificial Intelligence.

The Air Quality Station will allow your city to monitor key pollution parameters through Artificial Intelligence
More granularity to measure AQI in the city
Cities require Reference Air Quality stations to monitor key pollution parameters. These stations have high costs and their size is significant.
A higher spatial granularity is needed with a much larger number of reference stations spread throughout the city.
Libelium can solve this by providing smarter Air Quality Stations that can be distributed in the key points of the smart city.
AQI measurement solution
The new Air Quality Station has been designed to integrate Artificial Intelligence to create predictive models that you can manage through Libelium Cloud.
The quality of the reference data directly affects the results: good data range and resolution generate better A.I. models.
We made the difference
✓ GRANULARITY: Affordable, small and accurate stations, so that its deployment can cover more of the city’s key areas.
✓ TESTS & RESULTS: Take a look at the most recent studies we published and discover how the trained algorithm lead us to get the best R² and MAE in the market.
✓ TWO CALIBRATION OPTIONS: To apply the Artificial Inteligence models, Air Quality Station needs to be calibrated first. We offer two types of calibration options.
| ➀ Granularity | ➁ Tests and results | ➂ Two options for calibration |
|---|---|---|
| The more monitored locations in the city, the faster the response can be. | Check the results on the installations where the Air Quality Station has been deployed. | Co-calibration against the nearest reference station |
| Allows for a wider range of deployment and capillarity | Terrasa - Zaragoza (Roger de flor) - Zaragoza (Jaime Ferrán) | Calibration using the universal models provided by Libelium |
1. Parameters that can be measured
Air Quality Station allows you to measure the most relevant pollutants and key parameters required in every air quality project.
- Particulate matter (PM2.5, PM10)
- Different gases: CO, NO2, NO, O3, SO2
- Weather Station: Wind and compass, precipitation, temperature, humidity and pressure or solar radiation
- Noise Level
2. The Air Quality Station that learns
Co-location calibration against Reference Station
Step 1: Co-location phase: Air Quality Station will be deployed next to the reference station to collect data for 1 month. This is needed in order to calibrate Air Quality nodes against scientific reference stations.
Step 2-3: Data from the Reference station will be sent to Libelium Cloud through a CSV file. Meanwhile, all data gathered by Libelium Air Quality Station has been collected in the cloud.
Step 4: Then the calibration process starts in the Model Factory section from our Cloud. This is where Artificial Intelligence takes part, allowing the user to start predictive models.
Step 5: Once the AQS node has been calibrated and trained it is ready to be deployed.
*Remember that you can calibrate against the reference station more than one AQS node at the same time.
Calibration against Golden node
Step 1: Co-location phase: Your Air Quality Station previously calibrated against Reference Station is now named Golden Node.
A “golden node” is an Air Quality Station node previously calibrated by co-location process. This means that a first “Co-location” phase must be completed prior defining the device as “golden node”.
*This phase is interesting in case the project requires a large number of Air Quality Stations. In this way, it is possible to calibrate the remaining nodes with the node that was calibrated against the Reference Station in phase 1 (now called Golden Node).
Apply Universal Models
There are many barriers to accessing a reference station. That is why at Libelium we provide an alternative option for those users who do not have access to reference stations.
The collected data layer from different locations analyzed in the recent studies allowed us the design of a generic artificial intelligence model for air quality prediction.
Moreover, Libelium Air Quality Station’s universal model continues to learn and train itself from all Air Quality Stations deployed and placed next to reference stations, so it will become richer, more dynamic and more accurate.
Steps to follow:
Step 1: Different Libelium Air Quality Stations were deployed near Reference Stations and the collected data from the Reference stations will be sent to Libelium Cloud to shape the universal model.
Step 2: Now your Libelium Air Quality Station can work with the calibration against the universal model.
3. Air Quality Station + Libelium Cloud
Data extracted from Scientific Reference Air Quality station is used in Artificial Intelligence (AI) model automation specifically for every project.
Libelium Cloud is the new software platform that allows the management of an IoT project from the beginning to the end.
