TCS34725 Color Sensor RGB Color Detect Color Sensing Recognition Switch Module Color Unit GROVE I2C

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 coordinates (x, y).

Chromaticity Calculation Process Overview:

When we get coordinates (x, y), please reference the below figure so as to get the recommended color.

This Unit communicates with the M5Core via the GROVE A interface(I2C). Address is 0x29.
