Generic GY-31 TCS3200 Color Sensor Module (No Header) - I2C Interface
The GY-31 TCS3200 Color Sensor Module is a programmable light-to-frequency converter for precise RGB and clear light detection, compatible with 3.3V/5V microcontrollers like Arduino, Raspberry Pi, and ESP32. It provides digital output for color sorting, ambient light sensing, and material identification applications.
Features
- TCS3200 RGB Color Sensor with programmable photodiode array
- Wide 3V to 5V DC operating voltage range for microcontroller compatibility
- Digital frequency output simplifies interface with MCUs
- Optimized for close-range detection (~1cm) under controlled white light
- Compact module format requires user-soldered headers for connection

The GY-31 module integrates the TCS3200 programmable color light-to-frequency converter. The sensor uses an 8×8 array of photodiodes with red, green, blue, and clear filters, whose outputs are combined and converted into a single square wave with a frequency proportional to light intensity. This digital output method provides superior noise immunity compared to analog sensors.
Designed for integration into embedded systems, the module requires an external white LED light source and operates best at a short detection distance of approximately 1cm. Its digital interface allows direct connection to microcontroller I/O pins for frequency measurement, making it suitable for precise color analysis and sorting tasks in automated systems.
