  12 description: |
  13   The VCNL3020 is a fully integrated proximity sensor. Fully integrated means
  14   that the infrared emitter is included in the package. It has 16-bit
  15   resolution. It includes a signal processing IC and features standard I2C
  16   communication interface. It features an interrupt function.
