LDL-S High Precision Laser Distance Sensor 0.1 mm

Precision Meets Performance – Next-Level Accuracy for Demanding Applications

Introducing the LDL-S, our latest Laser Distance Sensor 0.1 mm, designed to deliver exceptional measurement accuracy, reliability, and versatility across a wide range of industrial applications. As an upgrade to the popular LDL series, the LDL-S takes performance to the next level with enhanced measurement capabilities, offering:

• Measurement range up to 80 meters

• Accuracy up to ±1 mm

• High-frequency measurements up to 30 Hz

• Support for multiple interfaces: TTL, RS232, RS485, Bluetooth

• Compatible with Arduino, ESP32, Raspberry Pi, PLCs, and more

What’s New in LDL-S Laser Distance Sensor 0.1 mm?

The LDL-S High Precision Laser Distance Sensor 0.1 mm is engineered for situations where accuracy and speed are critical. Compared to our previous LDL models, this version offers:

• Greater Range: Extended measurement distance up to 80 meters

• Higher Accuracy: Precision up to ±1 mm, ideal for fine control applications

• Faster Response: 30 Hz measurement frequency for real-time monitoring and control

• Enhanced Light Options: Choose between red laser (610–690 nm) and green laser (510–550 nm) for better adaptability to different surfaces and lighting conditions

How It Works – Phase-Based Distance Measurement

LDL-S uses phase-shift measurement technology to ensure ultra-precise distance calculations. This method compares the phase difference between emitted and received signals, offering high stability and resistance to external interference. Compared with time-of-flight systems, phase-based measurement provides better consistency at short to medium ranges, especially when millimeter-level accuracy is required.

Red or Green – Your Choice

• Red Laser (610–690 nm): Cost-effective and suitable for general surfaces

• Green Laser (510–550 nm): Better visibility and performance on dark or highly reflective surfaces

Users can choose the appropriate laser color depending on the application scenario and environmental lighting.

Multiple Interfaces for Easy Integration

LDL-S supports a variety of transmission protocols to suit different development and industrial environments:

• TTL / RS232 / RS485: For traditional wired connections

• Bluetooth (optional): For wireless communication and remote configuration

Fully Developer-Friendly

Whether you’re working on a custom automation solution or a smart IoT project, LDL-S is designed for smooth integration. It’s compatible with:

• • Arduino – Ideal for beginners and prototyping. Use LDL-S with Arduino boards for basic distance measurement, object detection, or custom DIY automation projects.

  • ESP32 – Great for IoT and wireless communication. The LDL-S works seamlessly with ESP32 when you need low-power operation and Wi-Fi/Bluetooth connectivity for remote data transmission.

  • Raspberry Pi – Perfect for edge computing and advanced data processing. Connect LDL-S to a Raspberry Pi for real-time visualization, advanced filtering, or cloud integration.

  • PLC Systems – Designed for industrial environments. The LDL-S can be integrated into programmable logic controllers (PLCs) to enable smart automation in factories, warehouses, and processing lines.

  • And More! – We provide example codes, communication protocols, and technical support to help integrate LDL-S into custom microcontroller or industrial computer systems.

Application Scenarios

The LDL-S High Precision Laser Distance Sensor 0.1 mm is perfect for a wide variety of precision-demanding applications, including:

• • Industrial Automation: Real-time object detection, positioning, and size verification on production lines.

  • Robotics: Precision positioning and movement feedback for robotic arms and autonomous mobile robots (AMRs).

  • Warehousing & Logistics: Distance control for stackers, forklifts, and conveyor systems in smart warehouses.
