TCS230-Colour Sensor Module

This breakout board is a colour sensor based on TAOS TCS230 programmable colour light to frequency converter which combines configurable silicon photodiodes and a current –to-frequency convertor on single monolithic CMOS integrated circuit.

The light-to-frequency converter reads 8X8 array of photodiodes, each array could filter red, green, blue light or clear from the light source via two control pins(S2, S3) and output a square wave(50% duty cycle) with frequency directly proportional to light intensity(irradiance). The full-scale output frequency can be scaled via two control input pin(S0, S1). Digital inputs and digital output allows direct interface to a microcontroller or other digital logic circuitry.

The TCS230 senses colour light with the help of an 8 x 8 array of photodiodes. Then using a Current-to-Frequency Converter the readings from the photodiodes are converted into a square wave with a frequency directly proportional to the light intensity. Finally, using any Micro we can read the square wave output and get the results for the colour.
