Electronic-nose devices have received considerable attention in the field of sensor technology during the past 30 years, largely due to the discovery of numerous applications derived from research in diverse fields of applied sciences. Recent applications of electronic nose technologies have come through advances in sensor design, material improvements, software innovations and progress in embedded systems integration. In this study, we have developed a prototype of a portable electronic nose (E-Nose) comprising a sensor arrays of many commercially available sensors, a data acquisition interface and a microprocessor. A based on different detection principles and mechanisms, is closely correlated with the expansion of new applications. Electronic noses have provided a plethora of benefits to a variety of commercial industries, including the agricultural, biomedical, cosmetics, environmental, food, manufacturing, military, pharmaceutical, regulatory, and various scientific research fields. Experimental results indicate that the proposed system prototype is able to identify the fragrance of many fruits, namely lemon, banana, litchi and etc.
