Library

The DFRobot_VL53L0X library is required for this project. It can be downloaded from GitHub.

Communication Protocol Description

The sensor uses Gravity-I2C interface for communication.

Principle

The VL53L0X range finder is based on new Time-of-Flight (ToF) principle. It integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation FlightSenseTM patented technology. Its 940nm VCSEL emitter (vertical cavity surface emitting laser) is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer ranging distance, higher immunity to ambient light and better robustness to cover-glass optical cross-talk.
