SPD1200Z2 · 905 nm Laser Rangefinder Module

SPD1200Z2 accuracy and range test conditions

A range number needs a target and conditions. For the SPD1200Z2 the published figure is 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.. Accuracy: Current published table and archived factory PDF: ±0.2 m (d≤200 m); ±0.5 m (d≤400 m); ±(0.5 m + 0.001d) (400 m<d<1,200 m). Archived factory DOCX: ±0.3 m (d≤100 m); ±(0.3 m + 0.0007d) (100 m<d<1,200 m). Sources differ; confirm the supplied configuration. d is distance in metres..

How to read the conditions

Reflectivity is the fraction of laser light the target returns: a white board is about 90 percent, a building about 70 percent, grass and soil 10–30 percent. Visibility limits long-range figures because haze absorbs the pulse both ways. When two modules quote different targets, convert both to the same target before comparing; the open module database lists every vendor's condition next to its number.

FAQ

What is the maximum range of the SPD1200Z2?

The published range is 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.. A range figure is only comparable together with the target and conditions it was measured on, so the condition is listed next to the value.

Which interface does the SPD1200Z2 use?

The published communication interface is UART-TTL, Customizable @ Default 115200bps, Optional 9600bps.

What laser wavelength does the SPD1200Z2 use?

The published wavelength is 905nm±5nm; laser safety entry: IEC CLASS I.

How much does the SPD1200Z2 cost?

The published single-unit price of the SPD1200Z2 is $150. Prices include shipping and are ordered directly from erdilrf.com.
