just a quick question. I want to know if it is possible to use the TCS3200 color sensor without the 4 LEDs included on the breakout board. I want to get the sky colors. Is that possible?

1 Answer 1


The photodiodes in the device itself have filters so it should theoretically be possible to use it without auxiliary light sources. Note, however, that the green and blue sensors have two sensitivity peaks and so using it outdoors without an infrared filter is not advised.

  • So how could I use the sensor without LEDs? I want to operate it using solar power and can't waste any energy. Can I just bridge them? Will I damage anything by doing that? Also is there any DIY infrared filter that I could build use with materials normal people have at home?
