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 Lumispot LSP-LRF series？

按公开量程档和接口看，最接近的 ERDI 型号是 LRF0105C, LRF0310C, LRF0405C。下决定前核对各自的量程条件；厂商标的目标不一样。

哪款 Lumispot LSP-LRF series 的 ERDI 替代型号价格最低？

所列型号中 LRF0105C 公开价格最低，单价 $300 起，含运费。

哪款 Lumispot LSP-LRF series 的 ERDI 替代型号最轻？

LRF0609C 重 ≤ 62 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。
