This Arduino Light sensor can capture little change of light!!

To ease the difficult of using this light sensor, a Gravity Interface is adapted to allow plug&play. The IO sensor shield is the best match for this sound senor connecting to your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry Pi, intel edison, joule and curie.
