Colour Sensor TCS3200 Module

by Velleman

The TCS230 senses colour light with the help of an 8 x 8 array of photodiodes.

Then using a Current-to-Frequency Converter the readings from the photodiodes are converted into a square wave with a frequency directly proportional to the light intensity. Finally, using the Arduino Board we can read the square wave output and get the results for the colour.


  • high resolution conversion of light intensity to frequency
  • programmable colour and full scale output frequency
  • communicates directly with a microcontroller
  • single supply operation (2.7 V to 5.5 V)
  • power down feature
  • non-linearity error typically 0.2% at 50 kHz
  • stable 200 ppm/°C temperature coefficient


  • S0-S1: output frequency scaling selection inputs
  • S2-S3: photodiode type selection inputs
  • out pin: output frequency
  • OE pin: output frequency enable pin (active low), can be impending when using
