APDS-9930安高华三合一传

代理美国TAOS/台湾安高华、敦南科技、光宝、光宝闪光灯原装正品三合一传感器与闪光灯 二合一传感器:台湾安高华 APDS-9930
The APDS-9930 provides digital ambient light sensing
(ALS), IR LED and a complete proximity detection system
in a single 8 pin package. The proximity function off ers
plug and play detection to 100 mm (without front glass)
thus eliminating the need for factory calibration of the
end equipment or sub-assembly. The proximity detection
feature operates well from bright sunlight to dark rooms.
The wide dynamic range also allows for operation in short
distance detection behind dark glass such as a cell phone.
In addition, an internal state machine provides the ability
to put the device into a low power mode in between
ALS and proximity measurements providing very low
average power consumption. The ALS provides a photopic
response to light intensity in very low light condition or
behind a dark faceplate.
The APDS-9930 is particularly useful for display man-
agement with the purpose of extending battery life and
providing optimum viewing in diverse lighting conditions.
Display panel and keyboard backlighting can account for
up to 30 to 40 percent of total platform power. The ALS
features are ideal for use in notebook PCs, LCD monitors,
fl at-panel televisions, and cell phones.
The proximity function is targeted specifi cally towards
near fi eld proximity applications. In cell phones, the
proximity detection can detect when the user positions
the phone close to their ear. The device is fast enough
to provide proximity information at a high repetition
rate needed when answering a phone call. This provides
both improved “green” power saving capability and the
added security to lock the computer when the user is not
present. The addition of the micro-optics lenses within
the module, provide highly effi cient transmission and
reception of infrared energy which lowers overall power
dissipation.
