Digital RGB Sensor
A color sensor is a type of ''photoelectric sensor'' which emits light from a transmitter, and then detects the light reflected back from the detection object with a receiver.
A color sensor can detect the received light intensity for red, blue and green respectively, making it possible to determine the color of the target object.
Since the light source is not just red, but includes the red, green, and blue wavelengths, and the ratio between each of these lights can be calculated, it is possible to differentiate the appearance and color of target pieces.
By using a red wavelength photoelectric sensor, there are some color combinations, such as red and white, that are difficult to differentiate. A color sensor allows for stable detection, even for these kinds of difficult combinations.
