The TCS3200 Color Recognition Sensor Module is a programmable color detection module designed to identify and measure colors by converting light intensity into a frequency output. It uses an array of photodiodes with red, green, blue, and clear filters, allowing accurate color sensing and comparison. This module is widely used in color sorting machines, robotics, quality inspection, and educational projects involving color detection and analysis.
