SPD1200S2 · 905 nm Laser Rangefinder Module
SPD1200S2 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。SPD1200S2 的公开值为 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.)。精度：±0.3m (≤400m)±0.5m + d × 0.1% (400m＜d＜1,200m)。

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。

FAQ
SPD1200S2 的最大测程是多少？
公开量程为 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.)。量程数字只有连同测试目标和条件一起看才可比较，所以每个数值旁都列出了条件。
