APDS-9930 Proximity and Contactless Gesture Detection Gesture Sensor Ambient Light Sensor

APDS-9930 provides I2C interface-compatible ambient light sensor (ALS, Ambient Light Sensor) and proximity sensor with infrared LED in a single 8-pin package. The ambient light sensor uses dual photodiodes to approximate low lumen under 0.01 lux illumination The visual response of the human eye provides the high sensitivity that allows the device to operate behind dark glass. The proximity sensor is fully tuned for 100 mm object detection, eliminating the need for factory calibration of end devices and subassemblies. From bright sunlight to dark rooms, the proximity detection function works well. A micro-optical lens is added to the module to provide efficient transmission and reception of infrared energy, which can reduce overall power consumption. In addition, the internal state machine allows the device to enter a low-power mode, resulting in extremely low average power consumption.
