Broadcom's APDS-9930 is a digital I²C-compatible interface ambient light sensor (ALS) and proximity sensor with IR LED in a single 8-pin package. The ambient light sensor utilizes dual photodiodes to approximate the human eye response with a low lux performance at 0.01 lux. This high sensitivity allows the device to operate behind darkened glass. The proximity sensor is fully calibrated to detect objects to 100 mm, eliminating the need for factory calibration of the end equipment or sub-assembly. The proximity detection feature operates well in any lighting from bright sunlight to dark rooms. The addition of micro-optic lenses within the module provides highly efficient transmission and reception of infrared energy, lowering overall power dissipation. In addition, an internal state machine provides the ability to put the device into a low power mode between ALS and proximity measurements, providing very low average power consumption.
