The Color 5 Click Board™ is a colour sensing board, which utilises the P12347-01CT, an integrated colour sensing device. This sensor is able to sense the red (R), green (G), and blue (B) components of light, providing measurement via the I2C interface. Besides sensing R, G and B components, there is an IR sensor too, allowing this Click Board™ to sense the intensity of the infra-red spectrum. In addition, this sensor is equipped with 3 LEDs, one for each colour component of the white light: red, green and blue LEDs are embedded into the sensor itself. The combination of photo-sensing and photo-emission elements allows for yet another feature of this sensor - proximity sensing.
