Color Sensor RGB Unit (TCS3472)

Description

COLOR is color recognition unit integrated TCS3472. Like its namesake, COLOR is

able to detect color value and return RGB data to the host.

Identify color principle: In the TCS3472, a 3*4 array of filtered photodiodes and a

16 bit analog-to-digital converters are embedded. Of the 12 photodiodes, 3 have red

filters, 3 have green filters, 3 have blue filters and 3 have no filter(clear).

When detecting the color of an object, TCS3472 returns data from four channels:

red(R), green(G), blue(B) and clear(C)(non-filtered). The response from the red, green

and blue channels (RGB) can be used to determine a particular source’s chromaticity
