0012 description: |
0013 The VCNL3020 is a fully integrated proximity sensor. Fully integrated means
0014 that the infrared emitter is included in the package. It has 16-bit
0015 resolution. It includes a signal processing IC and features standard I2C
0016 communication interface. It features an interrupt function.
