In order to accurately identify air pollutants in the region, comprehensively improve the level of refined management, help prevent and control air pollution, and win the battle for blue skies, in May last year, the Shangyu District Ecological Environment Bureau, in conjunction with Bikong Environment, introduced drone-based mobile air monitoring to conduct the first patrol operation on air quality in Hangzhou Bay Park, thus deepening the prevention and control of air pollution in the park.
Unmanned aerial vehicle (UAV) mobile monitoring equipment integrates UAVs equipped with high-definition aerial probes, high-definition cameras, and onboard intelligent gas sensors, providing functions such as mobile monitoring, image capture, and atmospheric monitoring. By using UAV technology to set flight areas and routes, it enables comprehensive monitoring and filming of pollutant emissions such as smoke, sulfur dioxide, nitrogen oxides, particulate matter, and VOCs from polluting entities within the designated area.
By conducting drone aerial surveys of PM2.5 and VOCs pollution sources in key areas, the pollution points were located with comprehensive coverage. Relevant technical personnel then drew pollution maps based on the total concentration of pollutants monitored. The pollution maps can intuitively reflect the pollutant emissions of enterprises or specific areas, and comprehensively and quickly identify key pollution areas. On that day, a total area of 1.5 km2 and 6 enterprises were inspected on site.

UAV-borne intelligent gas sensors can perform numerical monitoring of atmospheric parameters such as PM2.5, PM10, SO2, H2S, NO2, CO, O3, and TVOC. By monitoring pollutant data within a grid area in real time, it can quickly, accurately, and effectively understand the pollution sources within the grid, precisely locate the pollution sources, and assist in targeted pollution control. From the drone's high-altitude perspective, the exhaust emissions of industrial parks and key polluting enterprises are clearly visible, achieving a breakthrough from planar to three-dimensional inspection, which will greatly improve the quality and efficiency of environmental law enforcement.
The following sensors can be used for UAV-borne intelligent gas sensors (PM2.5, PM10, SO2, H2S, NO2, CO, O3, TVOC):
