Short summary

Low-cost sensors see additional pollution that is not seen with traditional regional air quality monitoring stations. This additional local pollution is sufficient to cause exceedance of the World Health Organization exposure thresholds. Analysis shows that a significant amount of the NO₂ pollution we observe is local, mainly due to road traffic. This article demonstrates how networks of nodes containing low-cost pollution sensors can powerfully extend existing monitoring programmes.
