Color and Digital Mark Sensors
Color recognition is by measuring the intensity of RGB three-color light, according to the R·G·B ratio to detect and distinguish different colors. The digital mark sensor uses RGB three-color light, the detection distance is relatively close, you can choose to set the color scale with the best reflection amount, and then compare the reflected light amount of the background color. The colour sensor uses variable white light with a relatively long detection distance and can operate in multi-color backgrounds to more accurately capture subtle color differences on the surface of an object, and can detect up to 15 colors at the same time.
