  • Mimaq Mobile Air Quality Assessment

    1. 1. Mobile Individual Measurements of Air Quality Symposium Geo Matters, City Scatters TU Delft, Geomatics, 21 Oct 2010

    4. 4. What is MIMAQ • Real time air quality monitoring • Mobile sensors • Carried by volunteering participants • Visualization on maps and mobile Augmented Reality
    5. 5. Project • Dec. 2009: proof of concept during Copenhagen Climate Summit • Mar-Oct 2010: pilot in Leiden, The Netherlands • Supported by Digitale Pioniers, ministry OCW
    6. 6. Purpose • Create a real time air quality monitoring network. • Make the invisible environment visible. • Find out how hyper-local, personal measurements are perceived by the audience (volunteers). • Evaluation currently in progress. • Increase involvement of civillians in this expert area.
    7. 7. How does it work • The City Senspod device measures gas levels. • Data samples are transferred via Bluetooth. • Results are displayed... • on Google Maps • on mobile devices (Augmented Reality view) Internet
    8. 8. Measurements • Every second a sample is taken, including: • GPS location • Levels of NOx and CO • Temperature, Relative humidity • Noise level in dBA • We chose NOx as indicator for air quality, also for its correlation with PM10 and PM2.5 levels* * Source: ECN Petten
    9. 9. Map view • Example plot during morning rush hour • NOx levels (red = high) • Red track corresponds with traffic congestion
    10. 10. Augmented Reality view • Layar Augmented Reality browser (iPhone, Android). • NOx levels are rendered as “clouds” in the air.
    11. 11. Results • About a month worth of raw data, collected by five City Senspods. • Implemented map view and AR view. • Approx. 25 volunteers involved. • Preliminary calibration and interpretation, work in progress...
    12. 12. Limitations • Sensor calibration! • Influence of temperature, humidity and O3 • GPS accuracy (no valid data acquisition without GPS fix)
    13. 13. Highlights • Feedback from volunteers and test users • Wow this is impressive “Is this for real?” • Thought provoking. • Positive action, creates awareness of own behavior. • Excellent case for education. • Interest from public services (e.g. fire brigade) and health care sector.
    14. 14. Conclusions • The MIMAQ pilot shows that pollution measurement can be done on a qualitative level with simple, low- cost components. • With improved calibration and interpretation of results a complimentary measurement grid provides real-time and early-warning information. • MIMAQ can also play a role in popularization and democratization of environmental quality monitoring.
