LDL-S 1mm High Precision Laser Distance Module

High Accuracy Laser Distance Module for Industrial Integration

The LDL-S laser distance module is a compact and high-performance laser measurement sensor designed for industrial automation, smart devices, robotics, and embedded distance measurement systems. Based on advanced phase-shift measurement technology, the module delivers stable and precise distance measurement with up to ±1mm accuracy and a measuring range of up to 80 meters.

Featuring a compact size of only 27.87 × 16.57 × 7.01mm and a lightweight 2g design, the LDL-S distance sensor is ideal for applications where space and weight are critical. The module supports multiple communication interfaces including TTL, RS232, RS485, and Bluetooth, making it easy to integrate into Arduino, Raspberry Pi, ESP32, PLC, and other embedded control platforms.

With visible red laser technology operating at 610–690nm, users can easily identify the measurement point during debugging and development. The LDL-S laser measurement sensor is widely used in industrial automation, warehouse logistics, intelligent transportation, smart agriculture, robotics, elevator systems, and drone applications.

Whether you are developing a smart device, industrial control system, or custom automation project, the LDL-S laser distance module provides reliable, real-time, and high-precision ranging performance.

Overview of LDL-S Laser Measurement Sensor

The LDL-S is engineered for customers who require high accuracy, fast response speed, compact structure, and stable performance. It uses phase-shift laser ranging technology to achieve accurate distance measurement in complex environments.

Compared with traditional ultrasonic sensors or infrared sensors, laser distance sensors offer better precision, longer measuring distance, and faster response speed. The LDL-S distance sensor supports a maximum frequency of 30Hz, enabling real-time distance monitoring for dynamic applications.

How the Laser Distance Module Works

The LDL-S laser measurement sensor adopts the phase-shift measurement principle. This technology calculates distance by measuring the phase difference between the emitted laser signal and the reflected signal returned from the target object.

d=cΔϕ4πfd=\frac{c\Delta\phi}{4\pi f}d=4πfcΔϕ​

Where:

• $d$ = measured distance
• $c$ = speed of light
• $\Delta \varphi$ = phase difference
• $f$ = modulation frequency

Compared with traditional measurement technologies, phase-shift laser ranging offers several advantages:

• Higher precision
• Faster response speed
• Better anti-interference capability
• Stable long-distance measurement
• Suitable for continuous measurement applications

This technology enables the LDL-S distance sensor to maintain accurate and stable performance in industrial environments with ambient light interference.
