This sensor adopts TCS3200 programmable color light-to-frequency converter, it can be applied to colorimeter measurement such as color printing, medical diagnosis, calibration of PC color monitor as well as process control and color coordination in oil paint, textile, cosmetics and printing material industries.

 

TCS3200 is built on the principle of three primary colors. Concretely speaking, TCS3200 allows only one specific primary color to go through and blocks other primary colors if a specific color filter was chosen. For example, when red filter was chosen, only red light can pass through while blue and green lights will be blocked out, so that we can get the intensity of red light. The strength of blue and green lights can be got in the same way. Finally, By analyzing the light strength of these three color, we can recognize the color reflected onto TCS3200.
