LRF1830C · 1.54 µm Laser Rangefinder Module
LRF1830C accuracy and range test conditions
A range number needs a target and conditions. For the LRF1830C the published figure is ≥18,000 m to a 3 × 3 m object; line of sight; visibility ≥26 km; relative humidity ≤50% at 30 °C. Accuracy: ±2 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 LRF1830C?
The published range is ≥18,000 m to a 3 × 3 m object; line of sight; visibility ≥26 km; relative humidity ≤50% at 30 °C. 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 LRF1830C use?
The published communication interface is RS-422 in the specification table; TTL/RS-422 alternatives in the interface section.
What laser wavelength does the LRF1830C use?
The published wavelength is 1.54 µm ±0.02 µm; laser safety entry: Class I stated in the module document; complete configuration requires its own assessment.
How much does the LRF1830C cost?
The published single-unit price of the LRF1830C is $7,000, falling to $3,500 per unit at the largest published quantity band. Prices include shipping and are ordered directly from erdilrf.com.
