Lightware’s SF02 is a lightweight laser rangefinder module that provides fast and accurate distance measurements from 0-40 meters (0 to 130 feet).


This module provides fast and accurate distance measurement using pulse-laser time-of-flight measurements, it is not affected by wind, noise, ambient light, terrain, air temperature, or changes in baromatric pressure.

Using pulsed-laser time-of-flight measurements, the SF02 is not affected by wind, noise, ambient light, terrain, air temperature, or changes in barometric pressure. This sensor works both indoors and outdoors.

For a quick test, simply connect the SF02’s USB port to your computer and open a serial terminal. Set your terminal to 115,200 kbps and distances are immediately available.
