    This is CJMCU 9930 APDS-9930 Digital Proximity And Ambient Light Sensor For Arduino. The APDS-9930 provides digital ambient light sensing (ALS), IR LED, and a complete proximity detection system in a single 8 pin package. The proximity function offers plug and plays detection to 100 mm (without front glass) thus eliminating the need for factory calibration of the end equipment or sub-assembly.

    The proximity detection feature operates well from bright sunlight to dark rooms. The wide dynamic range also allows for operation in short-distance detection behind dark glass such as a cell phone.

    In addition, an internal state machine provides the ability to put the device into a low power mode in between ALS and proximity measurements providing very low average power consumption. The ALS provides a photopic response to light intensity in very low light conditions or behind a dark faceplate.
