Functional Description
Single measurement triggers one target measurement. For a low-reflectivity target, the source says the module repeats measurements until stable data is obtained, then returns the result through the serial interface.
Continuous measurement repeats target measurements. The formal table states 3-10 Hz adaptive; the functional section separately states typical 2 Hz or 5 Hz and a customized maximum of 30 Hz. These statements are preserved separately and are not merged into one guaranteed frequency range.
The source packing list contains one laser ranging module and one power cable. UART-TTL test software and protocol documentation are described as integration resources.

Pulsed Time-of-Flight Engineering Context
The public LR1000E2 source used here does not state the internal timing architecture. The equation below describes pulsed time-of-flight ranging generally and is not presented as an additional LR1000E2 specification.
Real performance also depends on target reflectivity and area, incidence angle, atmospheric attenuation, receiver aperture, background light, detector response, timing thresholds and contamination of the optical path.

Source-stated application context
Application labels indicate where the source proposes evaluation; they do not prove fitness without system testing.
- Night-vision devices, thermal imagers, telescopes and laser illuminators for auxiliary ranging
- Border-security monitoring, aviation, communications and railway systems
- Law-enforcement, smart-water-conservancy and outdoor-sports ranging scenarios
- Civilian UAV, outdoor-observation and surveying/mapping equipment, subject to system validation
Confirm before selection
- Define target size, reflectivity, incidence angle and required detection probability.
- Reproduce sunlight, visibility, weather and optical-window conditions in acceptance testing.
- Verify voltage tolerance, peak current, grounding, interface levels, baud rate and connector revision.
- Separate accuracy, repeatability and displayed resolution in host requirements.
- Confirm mounting datum, boresight, field of view, enclosure sealing and thermal path.
- Assess accessible emission and labeling again after integration into the finished equipment.
Questions to resolve before design release
Does the maximum stated range apply to every target?
No. Use the reflectivity and environmental conditions shown beside the range row. Smaller, darker, oblique or partially obscured targets and degraded visibility can reduce received signal.
Are resolution, repeatability and accuracy interchangeable?
No. Resolution is the reporting increment, repeatability describes variation under repeated conditions, and accuracy describes closeness to the reference distance under the stated test method.
Is the finished product automatically IEC Class I?
No. A module-level source statement does not replace the accessible-emission and failure-condition assessment of the finished equipment, its window, controls, service access and labeling.
Which documents control wiring and interface release?
The ordered connector drawing, pin definition and approved interface document control the design.
