+
+description: |
+ The VCNL3020 is a fully integrated proximity sensor. Fully integrated means
+ that the infrared emitter is included in the package. It has 16-bit
+ resolution. It includes a signal processing IC and features standard I2C
+ communication interface. It features an interrupt function.
+
+ Specifications about the devices can be found at:
