Evaluation of an Inexpensive Ozone Sensor For Mobile Monitoring

Air pollution control agencies around the country monitor ozone at fixed sites. However, estimating exposure to ozone at distances away from those sites is of high interest to the general public. Several commercial companies are now manufacturing inexpensive ozone sensors appropriate for personal use. However, these instruments are priced so that the typical individual could not easily afford them. The immediate objective of this study is to compare inexpensive ozone sensors, both against each other and research grade ozone sensors. Further more a broader objective would be to demonstrate how inexpensive sensors could be built for public and research use by connecting them to a microprocessor computer (Arduino or Rapsberry Pi).
