Artificial olfactory sensation for predicting odor pleasantness.

Our project Artificial Olfactory Sensation for Predicting Odor Pleasantness is an electronic device that detects the smell more effectively than the human sense of smell. It consists of a mechanism for chemical detection. This is an intelligent sensing device that uses an array of gas sensors that are overlapping selectively along with a pattern reorganization component. Now a day they have provided external benefits to a variety of commercial industries, agriculture, biomedical, cosmetics, environmental, food, water, and various scientific research fields. This device detects hazardous or poisonous gas which is not possible to human sniffers. The smells are composed of molecules, which have a specific size and shape. Each of these molecules has a corresponding sized and shaped receptor in the human nose. When a specific receptor receives a molecule it sends a signal to the brain and the brain identifies the smell associated with the particular molecule. They work in a similar manner to humans. It uses sensors as the receptor. When a specific sensor receives the molecules, it transmits the signal to a program for processing, rather than to the brain. [ABSTRACT FROM AUTHOR]
