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?
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.
