Procuring and deploying low-cost sensor networks: guidance and questions for low-cost and commercial AQ sensing networks

Low-cost sensors provide a novel opportunity to monitor air quality at unprecedented spatial resolution. Devices are available at capital costs which are significantly lower than traditional monitoring methods. Whilst such devices allow for greater spatial resolution of air quality data there are a number of important things to consider during the procurement and deployment of low-cost sensor networks. This briefing document identifies some key considerations for using low-cost sensor networks based on experiences drawn from the NERC and EPSRC funded WM-Air & Birmingham Urban Observatory projects
