This module is based on the TCS3472XFN color light digitizer as the core sensor, providing digital output for red, green, blue (RGB), and clear light sensing. The integrated infrared blocking filter minimizes infrared components in incident light, enabling accurate color measurement. It features high sensitivity, a wide dynamic range, and reduced interference from infrared and ultraviolet components for precise color detection. Includes detection and maskable interrupt functionality. Communication is supported via I2C interface. Designed for ease of installation and compatibility with various environments. The two-hole version includes two LED lights to illuminate the target object. Sample programs are provided for Arduino and STM32 platforms.Operating voltage: 3.3V/5V Logic voltage: 3.3V/5V Communication interface: I2C Pinout: VIN: 3.3V/5V power supply GND: Power ground SCL: I2C clock input SDA: I2C data input INT: Interrupt output (open drain) LED: Built-in light emitting diode Color: Black Material: PCB Size: 31.3 x 11 mm Package Contents: 1 x Color Recognition Sensor 1 x Straight Pin Header 1 x Curved Pin Header Note: Other items not included.
