LDL-T Laser Distance Measurement Module

for High-Precision Industrial Applications

Overview

The LDL-T is a newly released laser distance measurement module engineered for developers and integrators who demand exceptional accuracy, speed, and versatility. Designed around a refined phase-shift measurement engine, the sensor delivers repeatable, millimeter-level results across diverse working environments—whether on a factory floor, inside smart warehousing systems, or embedded in autonomous robotics.

Parameters

Phase-Shift Technology Inside

Traditional time-of-flight systems can struggle to combine long-range capability with sub-millimeter precision. The LDL-T solves this dilemma by using an advanced phase-shift ranging architecture. A continuous, modulated laser beam is emitted toward the target; the returning signal’s phase difference is correlated with distance. Because phase detection is highly resistant to noise, the module achieves reliable, one-millimeter resolution even at faster update rates. This technology positions the LDL-T as a true precision distance measurement sensor for demanding industrial tasks.

Red or Green: Choosing the Optimum Wavelength

Different projects call for different laser characteristics:

• Red Laser (610–690 nm) – Excellent for indoor automation, alignment, and positioning where ambient light is controlled.

• Green Laser (510–550 nm) – Higher eye-catching visibility and stronger performance on dark or highly reflective surfaces, making it ideal for outdoor setups and long corridors.

With a swappable emitter design, you can select the laser color that best suits your measurement scenario without redesigning the host system.

Seamless Integration with Industry-Standard Interfaces

To accelerate prototyping and production deployment, the LDL-T Laser Distance Measurement Module offers multiple communication channels:

Interface	Typical Use Case	Notes
TTL UART	Embedded controller boards	3.3 V logic-level communication
RS232	Industrial PCs, legacy equipment	±12 V signalling, noise-resistant cables
RS485	Multi-drop bus, long cable runs	Differential signalling, up to 1200 m
Bluetooth	Mobile diagnostics, wireless setups	App-based data logging

Whether you are building on Arduino for quick proofs of concept, deploying ESP32 for IoT connectivity, or integrating with PLCs in large production lines, the module’s protocol flexibility keeps your design cycles short.

Typical Application Scenarios

1. Automated Guided Vehicles (AGVs) – Accurate pallet positioning and obstacle monitoring in smart warehouses.

2. Industrial Robotics – Real-time tool offsets and object detection for pick-and-place systems.

3. Smart Logistics – Height verification and gap measurement on conveyor systems.

4. Construction Tech – On-site distance checks for interior finishing, partition layout, and façade alignment.

5. Research & Development – Precision range data for photogrammetry, augmented-reality mapping, and academic prototypes.
