The Broadcom APDS-9960 is a digital RGB, ambient light, proximity and gesture sensor device in a single 8-pin package. The device has an I2C compatible interface providing red, green, blue, clear (RGBC), proximity and gesture sensing with IR LED. The RGB and ambient light sensing feature detects light intensity under various lighting conditions and through various attentuation materials including darkened glass. In addition, the integrated UV-IR blocking filter enables accurate ambient light and correlated color temperature sensing.The proximity and gesture feature is factory-trimmed and calibrated to 100mm proximity detection distance without requiring customer calibrations. Gesture detection utilizes four directional photodiodes, integrated with visible blocking filter, to accurately sense simple UP-DOWN-RIGHT-LEFT gestures or more complex gestures. The addition of micro-optics lenses within the module provides high efficient transmission and reception of infrared energy. An internal state machine allows the device to be put into a low power state between RGBC, proximity and gesture measurements providing very low power consumption.It can be used in display backlight control,correlated color temperature sensing,cell phone touch-screen disable,digital camera touch-screen disable,mechanical switch replacement,gesture detection and so on.
