TCS3200 Color Sensor Module for Arduino | RGB Color Detection for MCU Projects

The TCS3200 Color Sensor Module for Arduino | RGB Color Detection for MCU Projects detects and measures the color of objects using an array of photodiodes with red, green, blue, and clear filters. It outputs a square wave with frequency proportional to light intensity for each color channel.

Key Features

• RGB + clear color detection using filtered photodiodes
• Programmable color filters for individual RGB measurement
• Frequency output – no ADC required on microcontroller
• Wide supply voltage range from 2.7V to 5.5V
• High resolution conversion with programmable scaling
• 4-LED illumination for consistent object lighting
• Compact module for easy integration

Technical Specifications

Applications

• Color sorting machines and automated quality control
• Ambient light sensing and color temperature measurement
• Colorimeter projects and paint matching
• Product quality inspection
• Interactive art installations
• Educational color theory demonstrations

Important Notes

• Requires consistent lighting – onboard LEDs help but ambient light affects readings
• Calibration against white reference needed for accurate color values
• Distance from object affects reading – maintain consistent positioning
• Shiny/reflective surfaces give inconsistent readings – matte surfaces work best
• Use TCS230 library (compatible) for Arduino
