The TCS230 is a programmable color light-to-frequency converter which combines configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit.
The color sensor module is made up of the color sensor itself and four Infrared LEDs which are used to illuminate any object placed in front of the sensor to ensure the readings are accurate and are not affected by the surrounding illumination. The sensor is made up of an array of photodiodes with color filters for red, blue, green and a clear filter on top.
