LRF50VB · 905 nm Single-Point LiDAR Sensor

LRF50VB 接树莓派:Python 串口读取

树莓派通过 /dev/serial0 以 460800 波特率读取 LRF50VB。PyPI 上的 erdi-lrf 包负责解帧;树莓派仓库另加了 CSV 记录、MQTT 发布和 systemd 服务。

开启串口

运行 sudo raspi-config → Interface Options → Serial Port:关闭登录 shell,开启串口硬件。接线 LRF50VB TX → GPIO15 (RXD),RX → GPIO14 (TXD),GND → GND。树莓派串口是 3.3 V;模块公开接口为 UART/IIC。

读一个距离

pip install erdi-lrf pyserial

python - <<'EOF'
from erdi_lrf import ErdiLRF
lrf = ErdiLRF('/dev/serial0', baud=460800, model='LRF50VB')
print(lrf.read_single())   # metres
EOF

日志、MQTT 与系统服务

erdi-lrf-raspberry-pi-python 提供 CSV 记录器、MQTT 发布器、MAVLink 桥以及开机自启的 systemd 单元。
