Interfacing APDS-9930 Ambient Light Sensor(ALS) with Arduino Uno

This module consists of ambient light , IR and proximity sensors. The detection distance is up to 100 mm. The APDS-9930 sensor measures the ambient light.

This sensor can also detect 0.01 Lux brightness in the dark. It can also be used behind dark glass like a mobile screen. For example, it turns off the touch screen during voice calls when your ear is close to the screen.

This sensor can be used to adjust the brightness of mobile backlight and the appropriate light response for various applications.
