GY-31(hw-531)Color Sensor Module is made using IC TCS3200, a programmable color light to a frequency converter.
It has configurable silicon photodiodes and a current to frequency converter in a single monolithic CMOS Integrated Circuit.
Its output is a square wave having a 50% duty cycle with frequency directly proportional to irradiance (light intensity).
This module can be directly interfaced with Microcontrollers, Arduino Boards, Raspberry Pi, etc.
