# 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](https://erdilrf.com)
- Source repository, validator and query tool: [github.com/ErdiTech/laser-rangefinder-module-database](https://github.com/ErdiTech/laser-rangefinder-module-database)
- Sortable web table: [erditech.github.io/laser-rangefinder-module-database](https://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.

### Coverage

| Manufacturer | Modules |
|---|---|
| ERDI LASER (ERDI TECH LTD) | 59 |
| Benewake | 12 |
| LightWare | 12 |
| JRT | 10 |
| Nooploop | 8 |
| Lumispot Tech | 4 |
| Garmin | 2 |
| DFRobot | 2 |

## Usage

```python
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/](https://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.

The compilation is released under the MIT license. Specification values remain the property of their manufacturers; this dataset only collects published figures with their source.
