Abstract:
-The electronic olfaction system or commonly referred to as an Electronic Nose is used to determine food flavoring scents. To be able to determine each scent, an array of proper sensors must be used so that they would respond to certain change in voltage levels when the scents are being injected through the chamber. Multi-channel ADCs with multiplexing capabilities are used for converting the analog signals, which would be fed to the interface card. The interface card acquires the converted analog signals from the ADC for software purposes. The data acquired are processed and analyzed by two programs, mainly the Visual C++ and MATLAB. Visual C++ is used to control the whole data acquisition and MATLAB for the artificial neural networks and training of the system. The type of ANN network used is back propagation, which is responsible for the training of the network of the different food flavoring scents. It also involves data banking and storing of data through a database. Identification of each scent is determined after the training of the system.
