LRF3000A1 · 905 nm Laser Rangefinder Module
LRF3000A1 ROS 2 driver: range node, topics, launch files
The ROS 2 package reads the LRF3000A1 over a serial port at 115200 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:=115200 -p model:=LRF3000A1Topics and parameters
| Name | Type / value | Note |
|---|---|---|
| /range | sensor_msgs/msg/Range | distance in metres, frame_id = lrf_link |
| port | string | serial device |
| baud | 115200 | published baud rate of the LRF3000A1 |
| model | LRF3000A1 | selects the frame profile |
Examples

FAQ
What is the maximum range of the LRF3000A1?
The published range is ≥3,000 m (70%-reflectivity building target; clear weather; visibility ≥4 km.). 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 LRF3000A1 use?
The published communication interface is UART, 3.3 V TTL @ 115200 bps default; 9600 bps.
What laser wavelength does the LRF3000A1 use?
The published wavelength is 905 ± 10 nm; laser safety entry: Class 1 (IEC 60825-1).
How much does the LRF3000A1 cost?
The published single-unit price of the LRF3000A1 is $200, falling to $80 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
