Hi,
I am designing photoelectric electric sensor of reflective type. I am detecting the objects of various colors.
When i place some objects of light colors like sky blue,grey... the detection is working. But when i place dark objects like red,black,green... the sensing is not happening for even a distance of about 10mm. I think these dark objects absorbs the light source and not reflect it back.
I am using a IR photo emitter with wavelength of 950nm by passing a current of 135mA (forward current of 150mA has given in datasheet).
What should i do to overcome this issue to detect dark color objects too..
Thanks,
Murugesh
