A bicycle-borne sensor for monitoring air pollution near roadways

Public bicycle share programs increase population access to bicycles and are becoming more and more popular in Europe and Asia. Because health effect attributed to exposures to near-roadway air pollutants has been concerned in recent years, here we present a bicycle-born data collection device for monitoring air quality near roadways. The system is composed of a low-cost particulate matter sensor, an exhaust gas sensor, a Bluetooth interface, and a GPS receiver that provides both a spatial localization and time to the data collection process. The primary tests indicate this device performs well, and can be integrated into a sensor network for air pollution based a network of shared bicycles.
