LRF3000A1 · 905 nm Laser Rangefinder Module
LRF3000A1 on Raspberry Pi: Python UART reader
A Raspberry Pi reads the LRF3000A1 through /dev/serial0 at 115200 baud. The erdi-lrf package on PyPI decodes the frames; the Pi repository adds a CSV logger, an MQTT publisher and a systemd service.
Enable the UART
Run sudo raspi-config → Interface Options → Serial Port: login shell off, serial hardware on. Wire LRF3000A1 TX → GPIO15 (RXD), RX → GPIO14 (TXD), GND → GND. The Pi UART is 3.3 V; the published interface is UART, 3.3 V TTL.
Read a distance
pip install erdi-lrf pyserial
python - <<'EOF'
from erdi_lrf import ErdiLRF
lrf = ErdiLRF('/dev/serial0', baud=115200, model='LRF3000A1')
print(lrf.read_single()) # metres
EOFLogging, MQTT and a service
erdi-lrf-raspberry-pi-python has a CSV logger, an MQTT publisher, a MAVLink bridge and a systemd unit that starts the reader at boot.

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.
