LRF200H · 905 nm LiDAR Distance Sensor
LRF200H ROS 2 driver: range node, topics, launch files
The ROS 2 package reads the LRF200H over a serial port at 460800 baud and publishes sensor_msgs/msg/Range in metres. Install from the driver repository, pass the port and model name, and the topic appears in RViz.
Install and run
cd ~/ros2_ws/src\ngit clone https://github.com/ErdiTech/erdi-lrf-drivers\ncd .. && colcon build --packages-select erdi_lrf_ros2\nsource install/setup.bash\nros2 run erdi_lrf_ros2 range_node --ros-args -p port:=/dev/ttyUSB0 -p baud:=460800 -p model:=LRF200HTopics and parameters
| Name | Type / value | Note |
|---|---|---|
| /range | sensor_msgs/msg/Range | distance in metres, frame_id = lrf_link |
| port | string | serial device |
| baud | 460800 | published baud rate of the LRF200H |
| model | LRF200H | selects the frame profile |
Examples
erdi-lrf-ros2-examples adds launch files, an RViz configuration, a fake node for bench work and median / outlier filters for the LRF200H.

FAQ
What is the maximum range of the LRF200H?
The published range is 0.05–200 m (90% reflectivity); 0.05–70 m (10% reflectivity) (The two source values remain bound to their stated target reflectivity.). A range figure is only comparable together with the target and conditions it was measured on, so the condition is listed next to the value.
Which interface does the LRF200H use?
The published communication interface is UART, IIC.
What laser wavelength does the LRF200H use?
The published wavelength is 905 nm; laser safety entry: Class 1.
How much does the LRF200H cost?
The published single-unit price of the LRF200H is $250, falling to $100 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
