[PDF][PDF] Community Air Sensor Network (CAIRSENSE) Project: lower cost, continuous ambient monitoring methods
Presentation prepared for: 108th annual meeting of the air & waste …, 2015•archive.epa.gov
… Hand-held, short-term monitoring by citizens; bicycle-mounted sensors to map air quality.
3 … Stationary multipollutant sensor deployment in a community; portable sensors for
harder-tomeasure pollutants. … Field utility: The SM50 provides analyzer-like performance,
with 1ppb detection limits, yet cost as much as 4-5 times less then the most cost effective
ozone analyzers on the market. But it has higher power draw than other …
