Drones with low-cost air quality sensors can improve air quality monitoring

A drone equipped with low-cost air quality sensors has revealed unexpectedly high concentrations of particulate matter at around 100 meters above ground level in Delhi. These new vertical insights could play an important role in urban haze understanding and mitigation. The findings, published in npj Clean Air, demonstrate the feasibility of measuring air pollution up to 100 meters using an affordable, custom-built drone platform.
