Nature kind of odor tens of thousands, even professionals specializing in odor identification work is often recognition errors.Keywords: electronic nose computer technology developed olfactory organs physiological reaction "Customs" security monitoring neural networks odor sensor identification infrared sensorIntroduction: The electronic nose developed a high-tech products is simulated animal olfactory organ, scientists are still not all clear principle of the animal's sense of smell. However, with the development of science and technology, more authoritative some universities in the world have developed electronic nose has a wide range of applications, most notably to the number of the University of Hamburg, Germany, has absolute authority in the sensor field in the world today. Electronic nose is the response pattern to identify the odor of the gas sensor array electronic systems, it can be in a few hours, days or even a few months time within a continuous, real-time monitoring of the specific location of the odor condition. Identifying odor main mechanism of the electronic nose is that each sensor in the array has a different sensitivity of the measured gas. The core of the device of the electronic nose gas sensor. Gas sensors based on the principle of different type of metal oxide, electrochemical, and conductive polymer type, quality, photo-ionization type can be divided into many types. Currently the most widely used is a metal oxide.How it works: Electronic nose is mainly composed of...
