Interested in learning how the software behind a color sensor works? This demonstration shows how easy it is to analyze the color values and differences in eight paint samples.
True color recognition sensors “read” colors by emitting white light, analyzing three beams of reflected colored light (red, blue, green), then measuring the level of light reflected back on each wave length. The level of reflected light is compared to the value stored in the sensor’s memory. If the value is within its tolerance limits, recognition of that value triggers the output. Typical uses of true color recognition sensors include sorting by product color, or exactly matching a memorized color to that of a passing target.
