The Color 9 Click Board™ is a very accurate colour sensing Click Board™ which features Broadcom's APDS-9250, IR and ambient light sensor. It contains a specially designed matrix of photosensitive elements, which can sense red, green, blue and IR components. Four low noise 18-bit ADCs ensure the high dynamic range, making this sensor suitable to be used behind dark glass.
This sensor offers a fast I2C interface for communication with the host MCU. It is perfect for sensing subtle light changes, as it is equipped not only with the red, green, and blue (RGB) but also the infra-red sensor, allowing a very accurate measurement of the subtlest changes in light.
