Abstract:

A gas sensor based electronic nose system is developed for monitoring air quality dispersion in and around livestock barns. The mobile system can be used in various applications under laboratory and field conditions. The system consists of 10 metal oxide Figaro gas sensors and a temperature/humidity sensor integrated with custom made circuits and data acquisition software. The sensors are sensitive to major odorous compounds. The e-nose system provides an easy, cost effective and user friendly tool for air quality monitoring. There is a relationship with sensor responses and gas concentrations are linear. Therefore, instead of calculating concentrations using statistical methods such as PCA and ANNs raw sensor data is used to monitor air quality. In order to monitor spatial distributions of sensor responses Kriging method is applied. Interpolation maps for each sensor response are developed. In order to visualize the areas where air quality problems occur, response of an air quality module is used as reference. Results showed the effectiveness of the developed system and method.
