Laser rangefinder
Product manual
1. Overview
The lightweight, SF02/F laser rangefinder module is an essential addition to any system that needs fast, accurate and reliable
distance measurements.
Operating from a 9 V battery or a regulated 5 V DC supply, the SF02/F includes analog, digital and serial interfaces that can be easily
connected to an embedded controller or a standard processing platform such as Arduino
®
or Raspberry Pi
®
. Each interface on the
SF02/F can be configured using a simple software menu that is accessible through the built-in USB port.
The SF02/F works by measuring the time it takes for a very short flash of laser light to travel to an object and back again. The
accuracy of the measurement is not affected by the the color of the object’s surface or the angle of incidence of the laser beam to
the surface. The SF02/F is virtually immune to background light, wind, noise and other environmental interference.
The maximum measuring range of the SF02/F is 50 meters and readings are updated 32 times per second. There is an option to
smooth the distance measurements if higher resolution is required or use the raw results if higher speed is needed.
In addition to the easy-to-use USB and screw terminal interfaces, there are two expansion ports which allow for alternative access to
additional digital and analog signals within the SF02/F. The SF02/F can also be connected to a standard Arduino Uno compatible host
controller with an SF02/F Arduino shield.
