LightWare SF10/B


LightWare SF10/B


The LightWare SF10/B is a compact, lightweight laser altimeter for above-ground-level altitude measurement from small fixed wing or multi-rotor craft, with a range up of 50m.  

SKU # R370-SF10-B

Add To Cart

The SF10 series modules from LightWare provide accurate and fast altitude (AGL) measuring capability, regardless of terrain. Each includes digital (serial and I2C) and analog (12 bit) outputs along with a micro USB configuration port. The configurable features and multiple hardware interfaces make the SF10 easy to use with different types of flight controllers. The SF10 laser altimeter uses a time-of-flight (TOF) system to take accurate distance measurements to natural or artificial surfaces.

These units are easy to configure using the built-in menus and LightWare Terminal software (download below).  They ship fully calibrated, ready to run and include all necessary power, interface and USB cables.  

All necessary cabling included with sensor.
