Monitoring volatile organic compound by visual recognition technology of application

To recognize volatile organic compound for colorimetric sensor array which constitute with chemical dyes. The rapid and low cost system can identify dilute compound. Every different compound is presented specified color on the colorimetric sensor array. In this research, we use CCD (charge couple device) to clearly classify the change of color on base, and make sure what the compound would be by Neural Network model. Based on the experimental result, we totally test for 33 group data, and precisely classify all type of volatile organic compound. It's successfully to achieve the target in this research.
