GY-31 TCS3200 Color Sensor Module

The GY-31 TCS3200 Color Sensor Module is a digital color detection board that uses the TCS3200 sensor to measure the color of objects. It converts light intensity reflected from a surface into frequency output signals corresponding to red, green, and blue (RGB) components. This makes it ideal for color recognition, sorting robots, color-based automation, line tracking, and interactive projects requiring real-time color detection.

This module interfaces easily with microcontrollers like Arduino, ESP series, PIC, and others using simple digital input pins. Adjustable filters and selectable output scaling allow calibration for different lighting conditions and improved accuracy.
