Color Sensor

  • Sensor Chip: TCS3200 (RGB color detector)
  • Detects static color, the output is a square wave with frequency directly proportional to incident light intensity. Supports fill-light by onboard LEDs

Power: 2.7V ~ 5.5V
Ideal detection distance: 10mm
Dimension: 36.0mm * 20.6mm
Mounting holes size: 2.0mm

Sorting by color
Ambient light sensing and calibration
Test strip reading
Color matching

How to Use
In the case of working with a MCU:

  • VCC ↔ 2.7V ~ 5.5V
  • GND ↔ power supply ground
  • LED ↔ MCU.IO (controlling the 4 white LEDs)
  • OUT ↔ MCU.IO (RGB color output frequency)
  • S0/S1 ↔ MCU.IO (Output frequency scaling selection inputs)
  • S2/S3 ↔ MCU.IO (Photodiode type selection inputs)
  • S0/S1 selects the output frequency scaling factor, S2/S3 selects the color filter of red, green, blue, then OUT outputs a square wave with frequency proportional to the selected color intensity. The detected color can be determined by the ratio of the intensity of red, green and blue.
