Color Sensor, based on TCS3200, is a complete color detector capable of detecting static color. The output of the sensor is a square wave with frequency directly proportional to incident light intensity. It also supports fill light by onboard LEDs. It includes a TAOS TCS3200 RGB sensor chip and 4 white LEDs. The TCS3200 can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few. 

The TCS3200 Color Sensor board makes it very easy to sense and record the light intensity of the general red, green, and blue spectrums of visible light while rejecting IR from light sources. You can then use these color sensor readings for the purposes of logging and finding patterns, or creatively calculate and make control decisions in your electronic projects.
