|---|---|---|
| LR1000D23 | White building: 4 m – 1,000 m (max. 1,200 m at night); vegetation ≥ 750 m | The white-building, vegetation and night-time figures are separate source test cases. Numeric target reflectivity and atmospheric test conditions are not stated in the reviewed public technical table; confirm the applicable controlled document. |
| LR1000E2 | 4–1,000 m | Standard range; actual reach depends on target and environment. |
| LR1000E4 | 4–1,000 m | Standard range; actual reach depends on target and environment. |
| SPD1200N3 | 3–1,000 m | Building target; visibility ≥10 km; humidity ≤60% |
| LR1200D23 | 4 m – 1,200 m (max. 1,200 m) | Target reflectivity, target dimensions and atmospheric test conditions are not stated in the reviewed public technical table; confirm the applicable controlled document. |
| LR1200E2 | 4–1,200 m | Standard range; actual reach depends on target and environment. |
| LR1200E4 | 4–1,200 m | Standard range; actual reach depends on target and environment. |
| LRF1200A1 | 5–1,200 m | Building target; the source table gives ≥5–1200 m. |
| SPD1200N0 | Catalog range 0.2–1,200 m. A 1,500 m night-time figure appears in the source under special conditions and is not a guaranteed range. | SPD1200N0 controlled source technical table; strong sunlight or low visibility may reduce range |
| SPD1200N2 | Catalog range 0.2–1,200 m. A 1,500 m night-time figure appears in the source under special conditions and is not a guaranteed range. | SPD1200N2 controlled source technical table; strong sunlight or low visibility may reduce range |
| SPD1200N4 | Catalog range 0.2–1,200 m. A 1,500 m night-time figure appears in the source under special conditions and is not a guaranteed range. | SPD1200N4 controlled source technical table; strong sunlight or low visibility may reduce range |
| SPD1200S2 | Catalog range: 0.2–1,200 m. Sources also report a 1,500 m night-time maximum under special conditions; it is not a guaranteed range. | Strong sunlight or low visibility may reduce range. The night-time row does not state a numeric target reflectivity or visibility condition; confirm performance against your actual target and environment. |
| SPD1200Z2 | Catalog range: 0.2–1,200 m; strong sunlight or low visibility may reduce range. Sources also list a 1,500 m night-time maximum under special conditions; it is not a guaranteed range. | |
| SPD1200ZG | 0.1–1,200 m | Visibility ≥10 km; humidity ≤60%; building target |
集成
所有 UART 型号共用一套帧格式，文档在 erdi-lrf-drivers，附 ArduPilot、ROS 2、Arduino、树莓派和 STM32 示例。每个型号页都链接到各自的接线、驱动和价格页。
FAQ
哪款 1 km 激光测距模块 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 1 km 激光测距模块 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。
