BernardMarx:
More goodies from China arrived today.Got the sensor wired up, plugged 47K resistors just to test and getting readings up to ~3V in bright light.
Project for tomorrow: actually calculate proper resistor values for negative feedback,redesign illuminator (LED too close to sensor, just saturates it with light, no reflected reading at all), then get together a processing sketch so I can start visually checking the colours it is reading.
Hello BernardMarx,
I am working on the same model RGB color sensor (KPS-5130PD7C). And now i'm stuck with the amplifier circuit to convert current into voltage. Bcz the sensor has common cathode. I have seen your attached image "IMG_20140423_010240.jpg" it looks good. do you have the circuit diagram for this setup. It would be a great help for me.
Thanks in advance.
