The light source detecter makes used of the variation of the separated voltage by the resistivity of photosensitive resistance input to the singlechip. If the voltage higher than a worth, the singlechip will regard it as high voltage state, it means that the light source has been detected. Otherwise the low voltage state means the light source has not been detected.
