| Abstract | Health effects attributed to air pollution, especially ambi-ent fine particulate matter (PM2.5), become a global issue. The central environment monitoring networks provide lim-ited spatial coverage and no contextual information. How-ever, there is no solution to take contextual information, such as environmental and user behavioral factors, into ac-count, which is highly associated to the variability of air quality level and the complex relationship between air qual-ity and human activities. In this paper, we design, imple-ment, and evaluate a new context-sensing device for person-al air quality monitoring, namely AirSense. AirSense is a portable and cost-effective platform, which is equipped with a dust sensor, a global position system (GPS) sensor, a tem-perature and humidity sensor, and an accelerometer sensor. The development of such a user-centered and geographical-information integrated platform enables us to collect fine-grained air quality along with contextual information. We evaluate the platform across a set of focused settings, such as the indoor vs outdoor, walking vs in-vehicle, moving vs stationary, and an environment with various levels of dust. Meanwhile, a user study is conducted to verify that AirSense is capatable of performing the ambient air quality monitor-ing in daily life. We also discuss several other applications with the new context-sensing platform. |
