Environmental surveillance is a big thing, important to our health and to the integrity of the world we live in. To optimise the air quality assertion, we need better resolution (more monitoring units deployed) and better sensors. To help resolution, sensors will have to conquer more in the space of wearables but also be part of the places we live in, and that includes cities. This project will document an experimental setup to track pollution, ultimately turning to a device that can be used in cities, based on IOT topology.
