Benefits of low-cost air quality stations
- New opportunities to conduct monitoring in locations and situations where traditional systems are not feasible solutions.
- Higher spatial resolution of measurements.
- Better understanding of local air quality concerns.
- Enriched engagement for air quality communities and stakeholders.
Preliminary Results from our low-cost air quality station
Empa’s Laboratory for Air Pollution and Environmental Technology have co-located eight low-cost air quality stations (45 sensors) with traditional road-side instruments in Zurich, Switzerland. The initial results look promising.
Below are example datasets
Data adjusted for O3, temperature and humidity
Low-cost raw sensor data compared to reference site
Dataset based on determined correction function
