TCS34725 RGB Color Sensor Module — I2C | Arduino Compatible

The TCS34725 Color Sensor Module uses the ams TCS34725 IC to detect and measure red, green, blue, and clear (RGBC) light with exceptional accuracy. Its built-in IR blocking filter ensures true color readings by eliminating infrared interference, making it reliable even in varying ambient light conditions. With a 16-bit ADC per channel and programmable gain and integration time, it is one of the most precise color sensors available for microcontroller projects.
