Abstract

As sensor technology becomes more accessible, the development of low cost data collection systems is becoming more useful for both professional research and citizen science. This thesis explores the social and physical utility of low cost air monitoring (less than $200), and the design and implementation of a low cost sensor platform air monitoring system. Data is collected and analyzed from Ozone (O3), Carbon Monoxide (CO), Carbon Dioxide (CO2) and particulate matter (PM 2.5) sensors and compared with data from high accuracy instrumentation to assess the viability of using these low cost sensors for ambient air quality monitoring in research. The accuracy of these sensors varied greatly, but some sensors were accurate enough to gather quality lab data for a fraction of the cost of industry standard instruments.
