Description
TCS3200 Color sensor is a color recognition module. It is used to distinguish as well as to identify different colors. It detects a wide variety of colors based on their wavelength. Useful for color recognition projects such as color matching, color sorting, test strip reading etc.It consist of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. Main part of the module is the TCS3200 chip which is a Color Light-to-Frequency Converter. The white LEDs are used for providing proper lighting for the sensor to detect the object colour correctly. This chip can sense a wide variety of colours and it gives the output in the form of corresponding frequency.
The chip consist of an 8 x 8 array of photodiodes. Each photodiode have either a red, green, or blue filter, or no filter. The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal circuits includes an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.

- Programmable color and full-scale output frequency
To determine the color of an object the frequency from 6th pin is measured when each filter is activated.
| Photodiode type | S2 | S3 |
| Red | LOW | LOW |
| Blue | LOW | HIGH |
| No filter (clear) | HIGH | LOW |
| Green | HIGH | HIGH |
The module has an array of photodiodes with 4 different filters that is red, green, blue and others without. each of the filters has 16 photodiodes
