MI3 -p photosensitive sensor

Light sensor is the use of photosensitive element will light signal into electrical signal sensor, near its sensitive to wavelengths in the visible light wavelength, including infrared wavelength and ultraviolet wavelengths. Light sensor is not limited to light detection, it also can be used as a probe of other sensors and to test the many non-electricity, as long as these non-electricity converted to the change of the optical signals.
