The ALS (ambient light sensor) provides measurements of ambient light intensity which match the human eye’s response to light under a variety of lighting conditions, and through a variety of attenuation materials.
It is a photodetector that is used to sense the amount of ambient light present, and appropriately dim the device's screen to match it. The proximity detection feature allows a large dynamic range of operation for use over short distances and behind dark glass. These devices are intended for use in mobile phones and over longer distances for presence detection in computer displays and monitors.
This module is based on AP3216C that is an ALS and PS module that includes an ALS, a proximity sensor (PS) and an IR LED in a package. This module is very suitable for applications under the transparent or dark glass. 
The performance of the near-distant distances is better and is suitable for identifying objects at distances close to the good visibility area. This unit is specifically designed to eliminate the reflection of objects, such as black hair by using the multiple proximity control, multiple LED control and 10-bit ADC output.
