A color sensor, also known as a photoelectric sensor, emits light from a transmitter and then detects the light reflected back from the object using a receiver. These sensors can detect the intensity of light reflected from an object and differentiate between primary colors such as red, blue, and green. By analyzing the received light intensity for these colors, it becomes possible to determine the color of the target object. Color sensors are widely used in various applications, including medical diagnosis, color printing, computer monitor calibration, cosmetics, paint, textiles, and process control for printing materials.
