  Air quality and the presence of tiny particular matter are crucial factors in
human health, especially when considering urban scenarios. In this context,
smart mobility coupled with low-cost sensors can create a distributed and
sustainable platform for social sensing able to provide pervasive data to
citizens and public administrations. Sustainable and eco-aware decisions can
then be supported by empirical evidence, resulting in an improved life and city
administration. In this paper, we present ArduECO, a simple Arduino-based
wireless device able of collecting air quality data. Without loss of
generality, we have designed our device as a box that can be installed on a
bike; in this way, beyond private bikes, municipalities could exploit their
bike sharing fleets as pervasive sensing systems.
