LRF1200A1 · 905 nm Laser Rangefinder Module

LRF1200A1 accuracy and range test conditions

A range number needs a target and conditions. For the LRF1200A1 the published figure is 5–1,200 m (Building target; the source table gives ≥5–1200 m.). Accuracy: ±1 m (5 m ≤ L ≤ 100 m); ±(1 + 0.004L) m (L > 100 m).

Ranging accuracy	±1 m (5 m ≤ L ≤ 100 m); ±(1 + 0.004L) m (L > 100 m)	L is distance in meters.
Display resolution	0.1 m	Reporting increment, not ranging accuracy.
Measurement update rate	1–3 Hz

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 LRF1200A1?

The published range is 5–1,200 m (Building target; the source table gives ≥5–1200 m.). 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 LRF1200A1 use?

The published communication interface is UART, 3.3 V TTL.

What laser wavelength does the LRF1200A1 use?

The published wavelength is 905 nm; laser safety entry: Class 1 (source panel inconsistent; confirm).

How much does the LRF1200A1 cost?

The published single-unit price of the LRF1200A1 is $90, falling to $35 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
