The Applications of Portable Electronic Nose for Indoor and Outdoor Air Quality Assessments

摘要

The objective of this work was to demonstrate the capability of our lab-made portable electronic nose which has been developed to evaluate the smell in both outdoor and indoor environment. For indoor applications, the performance of indoor air purifier system to clean the accumulated smell in restaurant area with varying working conditions has been evaluated by the portable electronic nose. For outdoor applications, the portable electronic nose was used for identifying the sources of nuisance smell emitted from factory which disturbs the nearby communities and evaluating the performance of industrial exhaust gas and air pollutant control systems. The results from indoor and outdoor air quality assessments show that our lab-made portable electronic nose can provide visualization of smell which is easier for the users to plan about investment and management on air pollution control systems.
