question: Is it possible a light sensor detects specific color from the environment?
For Example, the sensor should be able to detect Black sheep?

thanks, Mrs/Mr engineers.

 

Hello,

Have a look at the attached PDF's.

You could only detect it if the background reflected more light than the black sheep. As theoretically black absorbs all of the light falling on it any other background would do. Assuming white light illumination. In practice real black objects do not absorb all of the light falling on them. A white object reflects all colours (Wavelengths. ) of light equally . To detect different colours you would need to use filters in front of the detector.

Your problem astounds like one for computer vision, not a color detector. Computer vision systems are now cheap and relatively easy, including purpose built hardware that uses deep learning to detect objects of interest. That's to "computing at the edge" for IoT, there are packages designed to do this, if you look around.

You beat me to it...………..
