Do you think this would be efficient in detecting IR wavelengths around 940 nm?

The Ratio of colors is more suited for detecting colour.
So It doesn’t matter what the absolute brightness of the colour is:

Blue / (Blue + Red + Green) = 0.1

This is probably what the ‘White’ reading is for:

Blue / White = 0.1

i.f ” If Blue ratio < 0.2 then object is blue”

Hello, may I ask the distance and beam angle of the color sensor? We need an answer for our research study.. thank you

I have been looking around and so far this is the only tutorial I could find that clearly lays out the calibration and mapping process. Thanks so much!

In reply to Sara Santos.

Thanks Sara for telling me about imgur. With my code modifications to Rui’s code I was able to consistently tell the flashlight charged up in about 90 minutes.

I found the damaged flashlight out on a walk but have now resurrected it. A HOBO data logger determines that it has a very bright white LED lasting about 5 hours. An “eyeball” test showed it gave useful light, walking around my darkened house and not stepping on my new kitten.
