Application note

VL6180X basic ranging application note

Introduction

The VL6180X is a proximity sensor based on ST’s patented FlightSense™ technology. The

VL6180X interfaces to your micro-controller via the industry standard I²C bus. The module

also includes an ambient light sensor (ALS).

This application note describes how to set up the VL6180X and perform range

measurements with the sensor.

Note:

Settings presented in this document are for test purpose only. Performance and reliability

not guaranteed.
