TCS3200-DB (#28302): Color Sensor Module

Product Overview

General Description
TCS3200-DB Color Sensor Daughterboard is a complete color detector, including a TAOS TCS3200 RGB
sensor chip, white LEDs, collimator lens, and standoffs to set the optimum sensing distance. It plugs
directly into the BASIC Stamp-2pe Motherboard (#28300), Propeller Backpack (#28327), MoBoProp
(#28303, a future product) and will also interface to any BASIC Stamp module or Propeller board using
the optional DB-Expander SIP Converter (#28325). The TCS3200-DB can detect and measure a nearly
limitless range of visible colors.
The TCS3200 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 square-wave output whose
frequency is proportional to the intensity of the chosen color.
Features
Sensor provides a readout of individual RGB color components as a digital frequency.
Onboard white LEDs can be gated on and off for ambient light subtraction.
The included 5.6mm lens provides a well-defined field of view.
Module is plug-compatible with Parallax motherboards.
Module can run from 3.3V or 5V logic supplies, plus 5V for the LED.
Applications
Test strip reading.
Sorting by color.
Ambient light sensing and calibration.
Color matching.
What's Included
What You Need to Provide
Parallax motherboard, or DB-Expander in conjunction with a BASIC Stamp or Propeller chip.

    If you have installed other AVR firmware, reload the GPIO3 hex file using the LoadAVR.exe utility before proceeding. The TCS3200-DB works best with the front surface of the printed circuit board located between 1" and 1 1/16" from the subject being sensed. For this reason, aluminum spacers are included, which can be affixed to form legs.

    These numbers are relative values for the red, green, and blue components of the color the sensor is looking at. With the TCS3200-DB perched on its legs atop a piece of white paper, you will notice that the LEDs form a bright spot of light in front of the lens. You may need to adjust the LEDs or the height a bit to make sure that the spots from both LEDs merge into a single round spot.

    RCTIME S2, 0, Id If, after executing this code, the TCS3200-DB is present in the socket tested, the variable Id will have a value of around 35. An empty socket will yield a value of 1, and other TAOS light-to-frequency daughterboards will identify with different values.
