TCS34725 RGB Color Sensor I2C Waveshare

The Waveshare TCS34725 colour sensor measures the RGB colour values of an object, with an IR blocking filter suppressing infrared. An LED on the module illuminates the object, and its brightness can be adjusted via PWM. Thanks to the level shifter on the board, the module works with 3.3 V and 5 V and thus suits Arduino, Raspberry Pi, ESP8266 and ESP32. Communication runs via the I2C bus.
