Color Sensor

Identifies the colour of an object in front of it by measuring red, green and blue components separately through filtered photodiodes. Onboard white LEDs provide consistent illumination so readings do not shift with room lighting. Common in sorting machines, colour-matching projects and educational robotics. One important practical note: it needs calibration against known reference colours before it gives useful results, and it works best at a fixed short distance from the target. Distinguishes colours, not just light and dark; Onboard white LEDs give consistent illumination; Frequency output easy to read on any digital pin; Selectable output scaling for fast or precise reading
