Color Sensor – TCS 3200

Color Sensor – TCS 3200

The Color Sensor – TCS 3200 is a complete color detector, including a TAOS TCS 3200 RGB sensor chip and 4 white LED’s. The Color Sensor – TCS 3200 can detect and measure a nearly limitless range of visible colors. Applications include test strip reading, sorting by color, ambient light sensing and calibration, and color matching, to name just a few.

The Color Sensor – TCS 3200  GBB For Arduino has an array of photo detectors, 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 square-wave output whose frequency is proportional to the intensity of the chosen color. The TCS 3200 and TCS 3210 programmable color light-to-frequency converters that combine configurable silicon photo-diodes 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 (ir-radiance). 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 micro-controller or other logic circuitry. Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a micro-controller input line. In the TCS 3200, the light-to-frequency converter reads an 8 x 8 array of photo-diodes. Sixteen photo-diodes have blue filters, 16 photo-diodes have green filters, 16 photo-diodes have red filters, and 16 photo-diodes are clear with no filters. In the TCS 3210, the light-to-frequency converter reads a 4 x 6 array of photo-diodes. Six photo-diodes have blue filters, 6 photo-diodes have green filters, 6 photo-diodes have red filters, and 6 photo-diodes are clear with no filters. The four types (colors) of photo-diodes are inter-digitated to minimize the effect of non-uniformity of incident ir-radiance. All photo-diodes of the same color are connected in parallel. Pins S2 and S3 are used to select which group of photo-diodes (red, green, blue, clear) are active. Photo-diodes are 110 μm x 110 μm in size and are on 134-μm centers.
