Range test conditions
| Model | Published range | Target and conditions |
|---|---|---|
| LR1500D23 | 4 m – 1,500 m | Target reflectivity, target dimensions and atmospheric test conditions are not stated in the reviewed public technical table; confirm the applicable controlled document. |
| LR1500E2 | 4–1,500 m | Standard range; actual reach depends on target and environment. |
| LR1500E4 | 4–1,500 m | Standard range; actual reach depends on target and environment. |
| LRF1500H | 0.05–1,500 m (90% reflectivity); 0.05–300 m (10% reflectivity) | The two source values remain bound to their stated target reflectivity. |
| LR2000E2 | 4–2,000 m | Standard range; actual reach depends on target and environment. |
| LR2000E4 | 4–2,000 m | Standard range; actual reach depends on target and environment. |
Integration
All UART models share one frame family documented in erdi-lrf-drivers, with ArduPilot, ROS 2, Arduino, Raspberry Pi and STM32 examples. Each model page links its own wiring, driver and price pages.
FAQ
Which is the lowest-priced 2 km laser rangefinder module?
Among the models listed, the LR1500E2 has the lowest published price, From $40 per unit with shipping included.
Which is the lightest 2 km laser rangefinder module?
The LR1500E2 at ≤10 g is the lightest of the models listed.
Why does every range figure show a condition?
Vendors measure range on different targets (white board, building, 10 percent reflectivity) and in different visibility. A number without its condition cannot be compared, so this page lists the condition next to each range.
