怎样公平比较
在相同目标反射率下比量程，确认接口和电平与你的主机匹配，再比较含运费的公开单台价格。ERDI 的价格和数量阶梯在各型号页公开；ArduPilot、ROS 2、Arduino 和树莓派驱动开源在 erdi-lrf-drivers。开放模块数据库 收录了两家的数据并注明来源。
FAQ
哪款 ERDI 模块最接近 Laser Technology TruSense S200？
按公开量程档和接口看，最接近的 ERDI 型号是 LRF600H, LR1000D23, LR1000E2。下决定前核对各自的量程条件；厂商标的目标不一样。
哪款 Laser Technology TruSense S200 的 ERDI 替代型号 价格最低？
所列型号中 LR1000E2 公开价格最低，单价 $30 起，含运费。
哪款 Laser Technology TruSense S200 的 ERDI 替代型号 最轻？
SPD1200N0 重 ≈5 g，是所列型号中最轻的。
为什么每个量程数字都带条件？
各厂商测量程用的目标不同（白板、建筑、10% 反射率），能见度也不同。没有条件的数字无法比较，所以本页把条件列在每个量程旁边。
