Community odor in industrial areas should be regularly monitored and controlled for human health protection. Wireless odor sensor is a new science-base approach highly promising for this application. In this work, wireless electronic nose has been developed for odor sensing by deploying commercial gas sensor arrays, microcontrollers and ZigBee wireless network. The system is applied for environment classification at various divisions in Bangpu industry near Swang Kaniwas rehabilitation center including tanning factory, dry leather area, bone factory, waste area and waste water treatment plant. Air data measured by multi-sensor arrays are delivered via ZigBee network to a database station where PCA as linear explorative technique analysis is used to obtain odor dispersion and air-quality classification. The ambient quality in Bangpu industrial park area has been successfully classified by the developed system. Thus, the wireless odor sensor approach has successfully demonstrated for industrial ambient quality monitoring, which is highly beneficial for human health protection.
