Gravity Analog Ambient Light Sensor

This ambient light sensor is analog and sends a variable voltage signal to the Arduino controller. It uses the PT550 light sensor, which is more sensitive than conventional sensors. The Gravity interface makes the sensor easy to use and allows for straightforward plug-and-play operation. The IO sensor shield can be used to connect to the Arduino. The sensor is compatible with an operating voltage of 3.3 V, which also makes it usable with Raspberry Pi, Intel Edison, Joule, and Curie. You can use the sensor to automatically adjust screen brightness.
