摘要：It was developed an “electronic tongue” – Electronic Tongue System (ETS), in Portuguese Sistema
de Língua Eletrônica (SLE) –, instrument employing an array of capacitive sensors. Experimental
data collected from several sensors are analyzed by Principal Component Analysis (PCA) and Artificial
Neural Networks (ANN) techniques using different tools that support each technique separately. This
work aims mainly to describe a software tool to perform the data acquisition and the computational tasks
involved in data analysis. Software modules were implemented for the PCA and ANN analysis and they
were integrated to the SLE instrument. Results obtained here are compared to the ones obtained using
other tools, such as WEKA and MatLab, in order to validate the software developed by us.
