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. Keyence Sensors are used to detect, measure, and inspect a target during a process to increase efficiency. The light sensor works by shining a white light at an object and then recording the reflected colour. It can also record the intensity of the reflection (brightness). Through red, green and blue colour filters the photodiode converts the amount of light to current. Most industrial color sensors contain a white light emitter and three separate receivers. There are usually three sets of color source or color filter with peak sensitivities at wavelengths that we identify as red (580nm), green (540nm), and blue (450nm).
The Color Sensor is a digital sensor that can detect the color or intensity of light that enters the small window on the face of the sensor. This sensor can be used in three different modes: Color Mode, Reflected Light Intensity Mode, and Ambient Light Intensity Mode. The colour sensor has three different modes: colour, reflected light intensity, and ambient light intensity. Vision sensors use images captured by a camera to determine presence, orientation, and accuracy of parts. These sensors differ from image inspection “systems” in that the camera, light, and controller are contained in a single unit, which makes the unit’s construction and operation simple.
The line tracking sensor works by detecting reflected light coming from its own infrared LED and by measuring the amount of reflected infrared light, it can detect transitions from light to dark (lines) or even objects directly in front of it. White light is composed of seven components. These colours are violet, indigo, blue, green, yellow, orange and red. Colour can clearly help organize, it shows differences among objects, and can give us clear visual signals.
