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 *erage 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 pur*e 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 *itions 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 s*ing 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.
