SPD1200N4 · 905 nm Laser Rangefinder Module
SPD1200N4 精度与量程测试条件
量程数字必须连同目标和条件一起看。SPD1200N4 的公开值为 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)。精度：±0.3 m (D ≤100 m); ±0.3 m + D × 0.7‰ (100 m < D <1,200 m)。
公开的量程、精度与更新率
| 参数 | 公开值 | 条件 / 备注 |
|---|---|---|
| Measurement range | 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 |

| Measurement frequency | 2–15 Hz or 4–15 Hz, adaptive | SPD1200N4 controlled source technical table; both alternatives appear in the same formal source row |
| Valid measurement rate | ≥98% | SPD1200N4 controlled source technical table |
| False-alarm rate | ≤1% | SPD1200N4 controlled source technical table |
| Baud rate | 115200 bps (default) | SPD1200N4 controlled source technical table |
怎么看测试条件
反射率是目标返回激光的比例：白板约 90%，建筑约 70%，草地和土壤 10–30%。能见度限制远距指标，因为雾霾会双程吸收脉冲。两款模块标的目标不同时，先换算到同一目标再比较；开放模块数据库 把每家厂商的条件列在数字旁边。
