LW20 / SF20 LiDAR sensor
Product manual
The LW20 is able to measure the first and last return signals when there is more than one
object in the laser beam.
Measuring the distance to the nearest object and the furthest object allows a drone to get
information about potential collisions with trees while simultaneously following the terrain at a
known height above ground.
Objects must be separated by approximately 5 meters before they are seen as separate return
signals.
There are three different ways to communicate with the LW20:
•
For machine-to-machine communication there is a built-in command set that uses ASCII
mnemonics. These commands work via the serial or the I2C ports.
•
For human-to-machine communication there is an internal menu system that can be
accessed using a generic terminal application via the serial port. The LightWare Terminal
application can be used for this.
•
For interactive and graphical communication there is a GUI based Terminal application
available from the LightWare website. This application also uses the serial port.
