General description
The TCS3472 device provides a digital return of red, green, blue (RGB), and clear light sensing values. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately. The high sensitivity, wide dynamic range, and IR blocking filter make the TCS3472 an ideal color sensor solution for use under varying lighting conditions and through attenuating materials. This data is transferred via an I2C to the host.

Evaluation Kit for TCS3472
TCS3472EvalKit
The TCS3472 Evaluation Kit comes with everything needed to evaluate the TCS3472 color sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with an USB cable), a TCS3472 daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the color sensor settings as the PIC takes the TCS3472 I2C digital outputs to calculate illuminance in lux and color temperature.
Please note that ams-OSRAM AG is discontinuing production of TCS3472.
