| Summary: | Electronic Nose is developed to function like a real nose in daily lives where its basic
principles come from the human olfactory (sensing) system. It is used as automated detection
and classification of odours, vapours and gases through several complex technologies. The
objective of this project is to identify two categories of smell which consists of four fruits and
four spices.
The whole system basically can be categorized into two main components, which are
hardware system and software system. The hardware system can be categorized into sensing
system, data acquisition. The software system can be categorized into classification and user
interface.The sensing system is constructed based on an array of seven Figaro gas sensors. With the aid
of LabVIEW, data acquisition program is developed, in capturing and collecting result from
the signals generated by the sensors. The Probabilistic Neural Network has been adopted for
the classification of various odours and a graphical user interface in displaying the
identification of the odour. Both the classification process and the graphical user interface are
developed by Excel and Macros (Visual Basic). |
