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

Key Features:

• Laser accurately detects surfaces and measures distance up to 40 meters (130 feet) where ultrasonic and infrared distance sensing are inadequate
• Outputs 12 readings per second for quick data refresh
• Supports USB, analog and digital interfaces for a variety of applications
• No calibration required – ready to use right out of the box
• Configurable voltage output and ground/object proximity alarm settings

Application Ideas:

• Distance detection for Unmanned Aerial Vehicles (UAVs) between craft and ground
• Calculating speed of moving objects or vehicles
• Measuring depth of materials (snow, fluid, sand) from above
• Counting passing objects

• Important Notes:

  The SF02 is a Class 1M laser under Food and Drug Administration Guidelines. Class 1M lasers are considered non-hazardous unless viewed with optical aids including magnifiers, binoculars or telescopes.
