Abstract: The common and effective technique to find the quality of tea is by sensor activities of the human called Tea Tasters. But this technique is most predictable in nature. For this reason very sophisticated sensor network has been designed. Electronic Nose is the most efficiently used to calculate the behavior and quality of black tea. An Electronic Nose sensor has been developed, consisting of an array of five AT-CUT 10 MHz QCM sensors. The array has been exhibits by the aroma characteristics of different types of black tea (CTC, Orthodox) and the response has been monitored online though Data Acquisition System. The data obtained in this manner has been clustered with the help of different algorithm(PCA,LDA). A BPMLP network has also been incorporated for the purpose of classification. The paper is concluded with comparison of cluster validity indices of original data with those of clusters obtained with different algorithms and the performance of the system which is very effective, is justified.
