The Color Bricklet can be used to extend the features of Bricks with the capability to measure color, color temperature and illuminance of a light source. Thus the Bricklet can measure the color of an object via its reflected light. To create a defined illumination and color temperature the Bricklet is equipped with a API switchable LED.
The Bricklet can be used for many purposes, e.g. sorting of objects by their color.
The Sensor is equipped with color filters for the colors red, green and blue (RGB). In the chart above the responsivity of the sensor in the given color range is shown. Additional to the color information (RGB) a fourth value is measured called "clear value" (C). This is the sensors value without any color filter. Each value of RGB and C is measured as 16bit value. From these sensor values the Bricklet computes two additional values: illuminance and color temperature each with 16bit resolution.
