LRF50H · 905 nm LiDAR Distance Sensor
LRF50H ROS 2 driver: range node, topics, launch files
The ROS 2 package reads the LRF50H 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:=LRF50HTopics 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 LRF50H |
| model | LRF50H | 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 LRF50H.

FAQ
What is the maximum range of the LRF50H?
The published range is 0.05–50 m (90% reflectivity); 0.05–15 m (10% reflectivity) (The two source values remain bound to their stated target reflectivity. The source marks this parameter as measured at 25°C in an indoor environment.). 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 LRF50H use?
The published communication interface is UART.
What laser wavelength does the LRF50H use?
The published wavelength is 905 nm; laser safety entry: Class 1.
How much does the LRF50H cost?
The published single-unit price of the LRF50H is $100, falling to $50 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
