M5Stack RGB Color Sensor Unit TCS3472

The M5Stack Color Unit uses the TCS3472 sensor to measure the red, green, blue and clear values of light. An IR blocking filter on the chip suppresses infrared, which improves the colour measurement. A white LED on the unit illuminates the object so that the colours are detected cleanly. It can be switched on and off by the program, for example only for the measurement.

The unit is connected to port A of an M5Stack Core or M5Stick and communicates via I2C at address 0x29.
