The Color sensor module base on TCS3200 which is a programmable color light-to-frequency converter, it could filter RGB data from source light and convert it to a square wave(50% duty cycle) with frequency directly proportional to light intensity (irradiance).
The full-scale output frequency can be scaled by one of three preset values via two control input pins(SO, S1 Selectable Options 2%, 20%, 100% frequency),and pin S2, S3 control the filter of RGB. Digital inputs and digital output allow interface to a microcontroller or other logic circuitry directly.
Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line. At last, user can calculate the color of the light by RGB values.
