I2C 1KHZ 100m Long Range LiDAR Module

Long‑range distance sensing has become a cornerstone of autonomous systems, industrial monitoring, and smart infrastructure. About PT-100H 1 kHz LiDAR module, with a usable detection range up to 100 meters and Class‑1 eye‑safe laser emission, this lidar module provides robust, cost‑effective ranging for outdoor and industrial environments.

Core Working Principle

1. This 100m lidar module uses direct Time‑of‑Flight (dToF) technology to achieve high‑precision long‑distance measurement.

2. emitter sends ultra‑short optical pulses, typically 940 nm invisible VCSEL.

3. The SPAD (Single Photon Avalanche Diode) array receives reflected photons.

4. The onboard processor calculates flight time and converts it into physical distance.

5. Built‑in algorithms suppress ambient light, multi‑path crosstalk, and surface reflectivity variations.

6. Unlike phase‑shift ToF or triangulation sensors, dToF lidar sensor maintains consistent accuracy across near‑to‑far ranges and performs reliably under strong sunlight up to 100k lux ambient immunity, making it ideal for outdoor 100 m‑class applications.
