Color sensor Color is one of the last qualities still being checked by human eyes in most applications. Color sensors such as the CS24D are changing this. Electronic color sensors are increasingly being used in automated applications to reduce automation errors and improve quality at production line speeds. Delta’s color sensors and sorters are based on our patented pulsed LED technology and offer the benefits of rugged, long-life, solid-state lighting with a wide range of colors from blue to near-infrared. While most color sensors use a single white LED and filtered detectors, Delta's color sensors are different. They use multiple ultra-high intensity LEDs for smooth, bright lighting and unfiltered large-area precision photodiodes for better signal-to-noise ratio. And the resulting large sensing areas provide superior performance on textured materials. Be confident the color you want is traveling down your production line. Delta’s color sensors provide superior performance in a wide variety of applications, even with textured and other difficult materials. Basic Color Sensor Suppose you have a sensor that can see many different colors, such as a photoresistor. How would you use this sensor to detect red apples vs. green apples? Well, consider brightness comparisons. Red apples reflect red light but absorb green light. Green apples reflect green light but absorb red light. If you shine a red light (such as from a red LED) on both apples, the red apple will reflect much more light than the green apple. As such, the apple that appears the brightest to your sensor will be the red apple. If you shine green light from a green LED on both apples, the green apple will appear the brightest.
