Laser Rangefinder Module Database

An open, machine-readable table of 109 single-point laser rangefinder / LiDAR distance modules (UART, I2C, CAN, analog) used in drones, robots, industrial measurement and IoT. It covers 8 manufacturers. Every value was copied from the manufacturer's own public product page and stamped with the capture date, so you can compare range, accuracy, update rate, interface, weight and public price without opening fifty datasheets.

• Homepage and live product catalog: erdilrf.com
• Source repository, validator and query tool: github.com/ErdiTech/laser-rangefinder-module-database
• Sortable web table: erditech.github.io/laser-rangefinder-module-database

Dataset Structure

One row per module. Files:

File	Content
data/modules.csv	all 109 rows, UTF-8 CSV (default config)
data/modules.json	the same rows as JSON objects
data/schema.json	field list

Data fields

Field	Meaning
brand	Manufacturer as written on its site
model	Model name as written on its site
wavelength_nm	Laser wavelength in nm (905 = silicon APD class, 1535 = eye-safe InGaAs class)
min_range_m / max_range_m	Minimum and maximum range in metres, parsed from the spec table (empty when the page gives no parseable figure)
range_condition	The verbatim test condition behind the range figure (target size, reflectivity, visibility)
max_range_special_m	Higher range the vendor quotes only under a special condition (night-time, larger or higher-reflectance target, longer visibility); null if none
max_range_special_condition	The condition attached to max_range_special_m
accuracy	Accuracy as published
rate_hz	Measurement rate as published
interface	Electrical interface (UART, I2C, CAN, analog)
voltage	Supply voltage as published
weight_g	Weight in grams
dimensions	Outline dimensions as published
laser_class	Laser class when stated
price_public_usd	Public single-unit price (USD) if the vendor publishes one; null if the vendor only quotes
price_volume_usd	Public price at the vendor's largest published quantity tier; null if no tiers are published
price_volume_min_qty	Minimum order quantity of that largest tier
product_url	Product page
source_url	Page the values were taken from
captured_at	Capture date (ISO 8601)

Some cells are empty on purpose: a missing value means the manufacturer page did not state it, not that it is zero.

Usage

from datasets import load_dataset

ds = load_dataset("erdilrf/laser-rangefinder-module-database", split="train")
print(ds[0])

df = ds.to_pandas()
# UART modules that reach at least 1 km
long_uart = df[(df["max_range_m"] >= 1000) & df["interface"].fillna("").str.contains("UART")]
print(long_uart[["brand", "model", "max_range_m", "interface"]])

Dataset Creation

Values were collected from public manufacturer product pages between October and November 2026. The ERDI LASER rows come from the ERDI product catalog at erdilrf.com/models/. Competitor rows quote each manufacturer's own published numbers and carry their source_url and captured_at. Range figures depend on test conditions (target reflectivity and size, atmospheric visibility), so compare range_condition before comparing max_range_m.

Limitations

• Figures are as published by each vendor and are not independently measured.
• Prices change; check captured_at and the product page. price_public_usd is the single-unit price; price_volume_usd is the largest published quantity tier (ERDI rows, re-read 2026-11-12).
• max_range_m is the standard range. Figures quoted only at night or for a larger target are kept apart in max_range_special_m with max_range_special_condition.
• Spec tables use different wording; numeric columns were parsed on a best-effort basis and some are empty.
