CJMCU 9930 APDS-9930 Digital Proximity And Ambient Light Sensor For Arduino

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 play 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 condition or behind a dark faceplate.

Note: The actual product may vary in terms of color and design.
