Detecting pollution with citizen science!

Using low-cost sensors, smart phones, wireless devices, and web, citizens can participate in democratized "citizen-sensing" projects to identify, and map, environmental pollution!



  2. Project: AirCasting #airpollution

  3. "participants can collect, map, and share data on sound in their environment, and using the AirCasting Air Monitor they can collect air quality data. Air quality data collection includes temperature, humidity, and even gas concentrations."
  4. Here's how to build an AirCasting Air Monitor: it costs around $180
  5. Project: Air Quality Egg #airpollution

  6. "The Air Quality Egg is a sensor system designed to allow anyone to collect very high resolution readings of NO2 and CO concentrations outside of their home" the data obtained is "uploaded in real-time to Xively, an open data service, which both stores and provides free access to the data" The eggs cost $240 each
  7. Project: Common Sense Research Project #airpollution

  8. Mobile phone technology, coupled with new sensing and software, could empower citizens to obtain measurements that means the most to them, those that capture the actual conditions they are currently experiencing, not citywide averages. This could help citizens decide which areas to avoid at a given time! This project, for instance, discovered several microclimates within San Fransisco.
  9. Linking real-time data on air pollution to signs around the city could enable citizens to avoid dangerous areas!
  10. Project: Stop Almond Brook Link Road in Wigan, UK #airpollution

  11. Citizens were concerned about harmful emissions from a proposed link road, and installed gas diffusion tubes to measure pollution
  12. What are diffusion tubes?
