摘要：
Quantification of tea quality based on its aroma characteristics using a portable/handheld device with a set of tea aroma volatile specific sensors and generic gas sensors is one of the valuable requirements in tea industry. Conventionally the tea quality parameters are quantified in a scale of 1 to 10 based on human senses by some professional human experts called "tea tasters". Electronic Nose has been successfully implemented for quality evaluation of finished tea as well as end-point detection of tea fermentation process. This paper includes the description of Handheld Electronic Nose (HEN) and its response in various tea aroma chemicals to validate the sensor array and the system. The overall system is based on a 16-bit microcontroller platform with touch screen as graphical user interface.
