Desirable Direction

  • Lower Cost Systems
  • Higher Spatial Resolution

Sensor Applications

  • Stationary Mode
    • Source Fence line
    • Community measurements
    • e.g.
      • Multipollutant sensor stations in near road
      • Community setting
  • Mobile Mode
    • Personal monitoring
    • Community group monitoring
    • Mapping spatial trends
  • Education Outreach
    • EPA ORD’s particle sensor kit
    • Instrumented kits measuring VOCs
    • Hacking fiber optic flowers to light up based on CO2 sensor readings (EPA ORD)

Additional Factors

Evaluation of Emerging Air Pollution Sensor Performance

The US EPA has focused a majority of its attention on sensors costing < $2,500.00 as it is believed such a cost would be at the upper limit to that which citizen scientists, as well as many others might be able to afford.
