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.

This adapter allows you to connect a barrel jack connector to bare wires. One end has screw terminals and the other has a 5.5x2.1mm, center-positive female barrel jack. If you have a power supply with a barrel jack and want to plug it into a breadboard, this might be the simple solution.
These 10 segment bar graph LEDs have many uses. With a compact footprint, simple hookup, they are easy for prototyping or finished products. Essentially, they are 10 individual BLUE LEDs housed together, each with an individual anode and cathode connection.
