Co-Location project

Project Details

The AirGradient co-location project focuses on improving the accuracy of low-cost air quality sensors by comparing them to high-precision reference monitors. By placing these sensors side-by-side (co-locating), the project gathers data to calibrate and enhance the performance of affordable monitoring devices. The sensor testing and calibration is done in various locations with different climatic conditions and air pollution mixes to characterise the measurement performance under a wide range of conditions. This initiative aims to make reliable air quality data more accessible, particularly in regions with limited monitoring infrastructure.

Community Impact

More accurate data will help to identify and fight air-pollution related health and climate risks. Data will be shared openly to drive sensor development and accuracy. E.g. Columbia University is already using them to develop a machine-learning based calibration system that doesn’t require a reference monitor.
