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:
