| 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. |
