ماژول سنسور غیر تماسی تشخیص نور و نزدیکی APDS-9930

APDS-9930 provides an I²C-compatible interface in a single 8-pin package ambient light sensor (ALS, Ambient Light Sensor) and proximity sensor with infrared LED's, where ambient light sensor is approximated using a dual LED illumination 0.01 lux under low lumens human visual response performance, high sensitivity can be provided so that the operation of the device in the dark glass. The proximity sensor can be adjusted through the full 100 mm object detection, eliminating the terminal equipment and sub-assembly factory calibration requirements. From bright sunlight to dark rooms, proximity detection feature can work well. Module was added to provide micro-optic lenses infrared energy efficient transmission and reception, can reduce the overall power consumption. In addition, the internal state machine allows the device to enter a low-power mode, bringing the average power consumption low.

Applications:
Adjustable light mobile phone backlight
Notebook / display security
ASutomatically enabled hands-free mode
Automatic menu pop up
Digital camera eye sensor
