The sensor works based on the theory of three primary colors. Therefore, knowing the proportion you can get the color of the tested object. For TCS3200, when a color filter is selected, it only allows a specific primary color to pass through and blocks the other two colors. For instance, when the red filter is selected, only the light of red color can pass through and that of green and blue is blocked. Thus, the value of red light can be obtained. Similarly the values of green and blue light are obtained. Then, based on the three values, the color of light reflected to the TCS3200 sensor can be analyzed.
The TCS3200 sensor has 4 types of filter and the filter is selected based on the high/low of pin S2 and S3 on the module. Also, the output proportion of the four filters can be selected by S0 and S1, as 100%，20%, 2%, or power down.
Application
The module is widely used in color digital camera, marine monitoring, atmospheric monitoring, color matching of color floor, etc.
