How to compare fairly
Compare range on the same target reflectivity, check that the interface and logic level match your host, and compare the published single-unit price including shipping. ERDI prices and quantity bands are public on each model page; drivers for ArduPilot, ROS 2, Arduino and Raspberry Pi are open in erdi-lrf-drivers. The open module database holds both vendors' figures with sources.
FAQ
Which ERDI module is closest to the Laser Technology TruSense S200?
By published range class and interface, the closest ERDI models are LRF600H, LR1000D23, LR1000E2. Check the range condition on each before deciding; the vendors quote different targets.
Which is the lowest-priced ERDI alternative to the Laser Technology TruSense S200?
Among the models listed, the LR1000E2 has the lowest published price, From $30 per unit with shipping included.
Which is the lightest ERDI alternative to the Laser Technology TruSense S200?
The SPD1200N0 at ≈5 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.
