An Affordable Vehicle-Mounted Sensing Solution for Mobile Air Quality Monitoring

This paper presents the first prototype of the Expo-LIS system and its preliminary laboratory and field experiments. The ExpoLIS system is composed of an affordable vehicle-mounted mobile sensor network and its supporting user-centred services whose aim is to provide citizens with real-time and dense spatiotemporal air quality data. A set of preliminary static laboratory experiments and dynamic field experiments were conducted, showing that the current prototype is already able to track changes in the air quality and provide citizens with access to these events via a mobile application.
