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

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.

1.EasyLoader is a simple and fast program burner, and each product page has a product-related case program for EasyLoader.

2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click "Burn" to start burning.

3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. Click here to view the driver installation tutorial:https://docs.m5stack.com/en/related_documents/establish_serial_connection
