Informatie (ENG):

The module is a complete color detector, including a TAOS TCS3200 RGB sensor chip and 4 white LEDs. It can detect and measure a nearly limitless range of visible colors, practically suitable for test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few. It has an array of photodetectors, each with either a red, green, or blue filter, or no filter (clear). The filters of each color are distributed evenly throughout the array to eliminate location bias among the colors. Internal to the device is an oscillator which produces a squarewave output whose frequency is proportional to the intensity of the chosen color.

TCS3200 Color Sensor
Itis a programmable color light-to-frequency converter that combines configurable silicon photodiodes and a current-to-frequency converter on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). In the TCS3200 sensor, the light-to-frequency converter reads an 8 x 8 array of photodiodes. Sixteen photodiodes have blue filters, 16 photodiodes have green filters, 16 photodiodes have red filters, and 16 photodiodes are clear with no filters. The full-scale output frequency can be scaled by one of three preset values via two control input pins. Digital inputs and digital output allow direct interface to a microcontroller or other logic circuitry. Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.

The four types (colors) of photodiodes are interdigitated to minimize the effect of non-uniformity of incident irradiance. All photodiodes of the same color are connected in parallel. Pins S2 and S3 (photodiode type selection) are used to select which group of photodiodes (red, green, blue, clear) are active. Similarly, the output frequency scaling selection can be carried out through pins S0 and S1. TCS3200 (available in SOIC-8 package with part number TCS3200D) is designed for singlesupply operation, and can be powered from dc 2. 7 to 5.5 volts.

TCS3200 Color Sensor Module
TCS3200 color sensor module is infact a standard breakout board with TCS2300D sensor at its heart, and 4 LEDs as support lamps. If you want to turn on these LEDs, you could connect the ‘LED’ pin on the 10-pin TCS3200 color sensor module to 5 volt (or a digital pin) to drive them. Basic schematic diagram of the TCS3200 color sensor module is given below for your quick reference.
