Teach your machine to distinguish specific hues with the GY-31 TCS3200. Unlike basic light sensors that only measure brightness, this sophisticated module utilizes a matrix of filtered photodiodes to analyze the Red, Green, and Blue (RGB) components of any object. It converts chromatic data into a precise frequency pulse, allowing your microcontroller to identify colors for sorting tasks or quality control systems.
Filtered Photodiode Array: Features a 64-bit grid of sensors with dedicated filters for Red, Green, Blue, and Clear light, giving you granular control over exactly which part of the color spectrum you want to analyze.
Light-to-Frequency Conversion: Outputs a square wave signal directly proportional to light intensity, meaning you can read color values using simple digital counters or timers without needing an Analog-to-Digital Converter (ADC).
Integrated White Lighting: Equipped with four onboard bright white LEDs that flood the target object with neutral light, ensuring accurate readings even in dim environments or inside enclosed project boxes.
Selectable Output Scaling: Allows you to scale the output frequency (2%, 20%, or 100%) via logic pins, making it compatible with slower processors or maximizing resolution for high-speed industrial automation.
Non-Contact Analysis: capable of "reading" the color of test strips, fruit ripeness, or printed labels from a short distance, perfect for building automated sorting machines (like M&M or Skittles sorters).
Wide Voltage Logic: Operates smoothly between 2.7V and 5.5V, ensuring direct compatibility with both 3.3V logic (like ESP32) and standard 5V systems without requiring level shifters.
