ColorPAL Color Sensor

  • 28380: ColorPAL Light Detector
  • 28380: ColorPAL Light Detector
  • 28380: ColorPAL Light Detector
Product ID: 28380
In Stock: 250


For sensing color, the ColorPAL uses its LED to illuminate a sample, one color component at a time, along with a broad-spectrum light-to-voltage converter to measure the light reflected back. The amount of light reflected from the sample under illumination from each red, green, and blue LED can be used to determine the sample’s color.

Key Features:

  • Detects a full range of colors, and outputs data as RGB (Red/Green/Blue) components
  • Supported by BlocklyProp blocks and Propeller C libraries, as well as BASIC Stamp and Arduino code
  • Detects broad-spectrum ambient light with sensitivity down to 44µW/cm2 per lsb
  • Plugs into servo headers (with optional cable) or wireless breadboards
  • Single-pin interface uses a simple serial protocol to define and initiate color detection and generation

Note: The ColorPAL works with non-fluorescent reflective surfaces, preferably those in contact with its light shroud. For a full comparison of the ColorPAL to the TCS3200-DB Color Sensor, please refer to the chart in the ColorPAL documentation, below.


  • Color detection and generation details handled by onboard microcontroller
  • Onboard EEPROM for saving custom color detection and generation programs
  • Autorun feature permits running a pre-designated EEPROM program with only a power supply
  • Generates 24-bit color using onboard RGB LED
  • Power requirements: 5.0 VDC
  • Communication: Serial 1-Wire (asynchronous serial, open drain)
  • Dimensions: 1.72 x 0.90 x 0.65 in (44 x 23 x 17 mm)
