Color Sensor Module TCS3200

This TCS 3200 color sensor module consist of a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The 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 color correctly. This chip can sense a wide variety of colors and it gives the output in the form of corresponding frequency. This module can be used for making color sorting robots, test strip reading, color matching tests, etc.

The TCS3200 chip consists of an 8 x 8 array of photodiodes. Each photodiode has 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 include an oscillator which produces a square-wave output whose frequency is proportional to the intensity of the chosen color.
