The LIDAR-Lite v3 is a compact optical distance measurement sensor, which is ideal for drones and unmanned vehicles.

LIDAR-Lite v3


LIDAR is a combination of the words “light” and “RADAR.” Or, if you’d like, a backronym for “LIght Detection and Ranging” or “Laser Imaging, Detection, and Ranging.” At it’s core, LIDAR works by shooting a laser at an object and then measuring the time it takes for that light to return to the sensor. With this, the distance to the object can be measured with fairly good accuracy.

By sweeping or spinning a LIDAR unit, systems can create detailed distance maps. Survey equipment, satellites, and aircraft can be equipped with complex LIDAR systems to create topographic maps of terrain and buildings. Luckily, Garmin™ has created a user-friendly LIDAR unit for your robotics and DIY needs!

Note that this uses a Class 1 Laser, if you are concerned about your safety (in short: A Class 1 laser is safe under all conditions of normal use).

CLASS 1 LASER PRODUCT CLASSIFIED EN/IEC 60825-1 2014. This product is in conformity with performance standards for laser products under 21 CFR 1040, except with respect to those characteristics authorized by Variance Number FDA-2016-V-2943 effective September 27, 2016.
