Mixed Signals at Large Scales: IoT Sensors for Air Quality Monitoring and Forecasting

Activity: Talk or presentationInvited talk at conference or symposiumScience to science


IoT sensors are extensively used in monitoring, detection and early warning contexts. They rely on a tight integration of sensory inputs and embedded data processing to autonomously cope with disturbances and unpredictability of the physical world. Air quality monitoring presents an interesting and challenging use-case for the IoT technology to provide sustainable and reliable measurements as well as accurate predictions. On the one hand, miniaturised chemical gas sensors require frequent recalibration, are power hungry or come with slow response times. Using these in large scale deployments is problematic due to high maintenance costs to replace batteries and reference-measure sensors’ signals. On the other hand, gathered datasets are sparse: they comprise only point measurements and require well-designed spatiotemporal prediction models to yield accurate forecasts. These forecasts are valuable for large-scale optimizations and control of local pollution sources to improve ambient air quality, in particular in urban areas.

In this talk, I will summarise my lessons learned from operating and modelling low-cost IoT sensors for air quality monitoring over the past 10 years and present recent research findings on how to make such measurement networks more sustainable, and the short-term forecasts obtained from measurement data more accurate.
