Developing a next generation air quality monitor

In this study, Sun et al. present the development and evaluation of a next generation air monitoring system with both laboratory and field tests. Multiple sets of the developed system were deployed in the Hong Kong Marathon 2015 forming a sensor-based network along a marathon route. Real-time air pollution concentration data were wirelessly transmitted and the Air Quality Health Index for the Green Marathon was calculated, which were broadcast to the public on an hourly basis. The route-specific sensor network showed somewhat different pollutant patterns than routine air monitoring, indicating the immediate impact of traffic control during the marathon on the roadside air quality. The study demonstrated the usefulness of the emerging sensor-based air monitoring technology in rapid network deployment to supplement existing air monitoring.
