The application of 14 sensors of iNose electronic nose in the identification of genuine and fake cigarettes: From the experimental results, the data of real cigarettes are close to each other. It can be seen that there are similarities in real cigarettes. The numerical points of real cigarettes are scattered, because Real smoke is the shredded tobacco of different brands. The false cigarettes marked with W are scattered farther than the real smoke (for example, the "wsh" group), which makes it easy to distinguish between true and false cigarettes. The 14-sensor iNose electronic nose can be used to identify genuine and fake cigarettes.

The 14-sensor iNose electronic nose is used for the identification of cigarette grades. From the experimental results, it can be seen that the data points of the three-level double-happiness cigarettes are arranged from left to right according to the grade from low to high, without overlapping phenomenon. better. It is feasible to test the iNose electronic nose of 14 sensors to detect the odor information of the whole box of cigarettes and distinguish different grades.

The application of 14 sensors of iNose electronic nose in the identification of cigarettes: It can be seen from the experimental results that the data points of Camel, Double Leaf and Zhongnanhai cigarettes are distributed in different areas without overlapping with each other, indicating 14 The sensor's iNose electronic nose distinguishes Camel cigarettes, double-leaf cigarettes and Zhongnanhai cigarettes. The 14-sensor iNose electronic nose can be used to identify cigarettes.
