Description :

DFRobot's new Analog Ambient Light Sensor for Arduino or Raspberry Pi with its brand new design and much more convenient to use. This sensor helps you to detect the light density and reflect the analog voltage signal back to the Arduino controller. You can set the threshold of voltage level to trigger another unit on the Arduino project.
We also use the environmental PT550 light sensor and it is more sensitive to light than normal one. Place check following improvement we made. We are always devoted to bringing better user experience.
The IO sensor shield is the best match for this sound sensor connecting to your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry Pi, intel edison, joule and curie.
