Ronan Doorley – Doctoral Researcher, Trinity College Dublin

  • Speaker Bio:

    Ronan is a Doctoral Candidate in the School of Engineering, Trinity College Dublin where he is currently finishing his PhD research. Prior to beginning his PhD, he graduated from Trinity as a mechanical engineer and also gained experience working in the IT and construction sectors. His research investigates the interactions between urban transportation, environmental pollution and public health. More specifically, he uses a combination of statistical modelling and environmental sensing to estimate and predict the health and environmental impacts resulting from increased adoption of sustainable modes of transport.

    Presentation title:

    Pervasive urban pollution sensing with low-cost mobile sensors.

    Presentation Synopsis:

    Traditionally urban air quality has been measured by sparse networks of fixed-site monitors with numerical dispersion models being used to estimate pollution levels between measurement sites. This approach has significant limitations, particularly in quantifying personal exposures and identifying pollution “hotspots”. However, recent advances in sensor technology, GPS receivers and low-power electronics make possible the measurement of urban pollution concentrations at high spatial and temporal resolution. This presentation will describe the development of a low-cost mobile environmental sensing node capable of accurately measuring concentrations of gases (NOx, CO, NO2) and particulates (PM1, PM2.5, PM10) in real time. Recent applications of the technology to exposure monitoring of urban pedestrians and cyclists will also be described.
