Hi, I am looking to create a sensor device that can detect and edge of a paper. For example say we have a plain surface with a 1mm black line and if a piece of paper was to cross this line then an LED should flash. Would anyone know if there is a IR sensor that would suit this type of scenario whe…

Would these sensor detect a piece of paper if it were to cross a 1mm line?
