Three families and what each is for
VB single-point LiDAR (3 models): LRF10VB, LRF22VB, LRF50VB. Gram-scale boards for robots, drone landing and short indoor runs; the smallest weighs 1 g.
H-series LiDAR distance sensors (6 models): LRF50H, LRF100H, LRF200H, LRF300H, LRF600H, LRF1500H. LRF100H to LRF1500H share one 33 × 34 × 18 mm body, so a design can move up in range without a new bracket, on a 9–36 V DC supply.
SPD1200 family (7 models): SPD1200N3, SPD1200N0, SPD1200N2, SPD1200N4, SPD1200S2, SPD1200Z2, SPD1200ZG. 905 nm modules of about 5–10 g with 1–1.2 km catalog range on a 3.3–5 V supply.
Interfaces and outputs
Every model in this category outputs over UART (3.3 V TTL logic unless the record says otherwise). 7 also list I2C: LRF22VB, LRF50VB, LRF100H, LRF200H, LRF300H, LRF600H, LRF1500H. None has a native analog 4–20 mA, RS-485 or CAN output; PLC and fieldbus systems use a UART-to-RS-485 or UART-to-4-20 mA converter at the sensor. Protocol frames, baud rates and checksums are on each model page and in the open-source drivers on the open data page.

How to choose a laser distance sensor
Up to 20 m indoors: a VB board is the lightest and cheapest option (from $6 for LRF10VB). 50–300 m: LRF50H to LRF300H (LRF100H and up share the same 33 × 34 × 18 mm body). Around 1 km: SPD1200 modules are the lightest; LRF600H and LRF1500H if you also need I2C. For longer distances see the long range laser sensor page, and for silos and tanks the laser level sensor guide.
Check three numbers against your installation: the minimum distance (some sensors do not read close targets), the accuracy at your working distance, and the update rate your controller needs.

FAQ
What is a laser distance sensor?
A sensor that sends a short laser pulse to one point and calculates distance from the round-trip time (distance = speed of light × time / 2). ERDILRF sensors output that distance over UART, and many also over I2C.
How accurate are laser distance sensors?
It depends on the model and the distance. In the catalog, VB and H sensors state ±5 cm or ±10 cm below 5–10 m and 1% of distance beyond; SPD1200 modules state ±0.2–0.5 m near range plus a small distance-proportional term up to 1.2 km. Each model page gives the exact figure and its test conditions.
How much does a laser sensor cost?
Published unit prices in this category start at $6 and go up to $180 for the lowest quantity tier, shipping included. Quantity tiers are listed on each model page.
Is there a laser that can measure distance?
Yes. Every model on this page is a laser distance sensor: it uses a 905 nm or 940 nm pulsed laser and a receiver to measure distance to a single point.
