HazeWatch

Project Introduction:

The Hazewatch project aims to crowd-source fine-grained spatial measurements of air pollution in sydney, and to engage users in managing their pollution exposure via personalized tools. Haze watch contains: accurate estimates of their pollution exposure.

  1. Mobile Sensor: measures air pollution while the user drives
  2. Smart Phone: uploads via 3G network to database
  3. Database server: stores pollution data and models pollution based on data
  4. Web interface: overlays pollution map and displays on Google maps
  5. Mobile App: Track the user, and computes their exposure a posteriori based on their location trace.

The data collection architecture in the Hazewatch project is based upon the idea of “crowd-sourcing” or “participatory sensing”. Users collect and contribute air pollution data obtained from personal sensing units, and the greater spatial density of data thus obtained from many users in turn gives each user more accurate estimates of their pollution exposure.
