CJMCU- proximity detection and non-contact gesture Gesture Sensor APDS-9930
APDS-9930 provides I2C compatible interface in a single 8-pin package ambient light sensor (ALS, Ambient Light Sensor) and proximity sensor with an infrared LED, where ambient light sensor using a dual LED approximated 0.01 lux illumination at low lumen human visual response performance, high sensitivity provided by such devices can operate in the dark glass. The proximity sensor can be fully adjusted 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. Micro-optic lens module was added to provide infrared energy efficient transmission and reception, can reduce overall power consumption. In addition, the internal state machine allows the device to enter a low-power mode, bringing the average power consumption low.
