Intelligent sensor system for selected environmental safety application

This study focuses on two objectives. The first objective is to develop an integrated sensor system, called electronic nose (E-nose). E-nose has the ability to detect selected gases in the air. In this study, the interests of gas are Volatile organic compound (VOC), Ammonia and Carbon dioxide. The second object is to evaluate a system that can discriminate arsenic contamination levels in water, the researchers call it Electronic tongue (E-tongue). The system is based on using interdigitated dielectric sensing mode. Finally, demonstrating both systems (E-nose and E-tongue) are capable of detecting the specific targets (pollutant/ contaminant) in selected environments (air/water)
