COLOR is a color recognition unit that integrates the TCS3472 color light-to-digital converter. It is capable of detecting colors and converting the detected color values into RGB data, which can be sent back to the M5Core.
The unit communicates with the M5Core through the PORT A interface using I2C protocol, with an I2C address of 0x29. This allows for seamless integration and communication between the COLOR unit and the M5Stack controllers, enabling accurate color recognition and analysis in your applications.

LEARN AND DOCUMENTS
although outer package for shipment was damaged, products were protected and they woks without problem; it means very good.
Sensitivity, accuracy and repeatability are enough for hobby use. Unfortunately led light intensity was too strong, but it cannot be turned off. I had to prepare physical light shade to weaken it.
This sensor detects the three primaries (RGB) and "white" to calculate absolute and relative color values.
The detection speed is quite fast, several times a second. But you'll need to linearly calibrate your detector to get a "reality-correct" result.
Fortunately the sensor curve is calibrated at the factory!
It comes with a quick and easy "Getting started" Arduino IDE .ino sketch so you can just plug it in and try it out.
There's MANY documents online for this sensor if you want to plunge into the depths of its workings and features. It's a popular and well recognised item.
ONE limitation you should be aware of: The two cool white LED's are wired directly to the Grove plugs power. This means you wont be able to turn these two white LED's off, in order to analyse colors produced by LED's/screens or anything else that emits its own light.
It's a great little product!
I bought this as a gift for my brother. He enjoys it enough that I'll probably pick up the same order for myself.
Compliant product, fast shipping.
Very professional looking! Good mail tracking.
