+
+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:
+  https://www.vishay.com/docs/84150/vcnl3020.pdf
