SPD1200N4 · 905 nm Laser Rangefinder Module
SPD1200N4 accuracy and range test conditions
A range number needs a target and conditions. For the SPD1200N4 the published figure is 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). Accuracy: ±0.3 m (D ≤100 m); ±0.3 m + D × 0.7‰ (100 m < D <1,200 m).

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 SPD1200N4?
The published range is 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). 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 SPD1200N4 use?
The published communication interface is UART-TTL (customizable) @ 115200 bps (default).
What laser wavelength does the SPD1200N4 use?
The published wavelength is 905 nm ±5 nm; laser safety entry: IEC Class I.
How much does the SPD1200N4 cost?
The published single-unit price of the SPD1200N4 is $90, falling to $35 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
