1.Operating Voltage:3.3-5V 

2.Communication Interface:analog voltage

3.Operating Principle:ambient light sensor can perceive ambient light conditions and infrom the chip of adjusting displayer backlight brightness automatically so as to decrease product power consumption.For example,in cellphone and laptop applications,the electricity quantity consumed by displayer can be up to 30% of total battery electricity quantity,and adopt ambient light sensor can lengthen the operating time of battery;on the other hand,ambient light sensor contributes to provide soft image display.When ambient light brightness is relatively high,LCD displayer will be adjusted to high brightness automatically;and when ambient light brightness is relatively dim,displayer will be adjusted to low brightness
