The LDL-T Laser Distance Sensor Module is a next-generation high-performance ranging solution, engineered for precision-critical applications in automation, logistics, robotics, and smart systems. Built on phase-shift laser ranging technology, the LDL-T offers millimeter-level accuracy over distances up to 80 meters, with a fast response rate of up to 30Hz.
Whether you're designing an automated warehouse, a precision robotic arm, or a field-deployable sensing platform, the LDL-T delivers the performance, size, and reliability your system demands.
Long-Range Precision
Accurately measure targets from 0.05 to 80 meters, even in dynamic or challenging environments.
Millimeter Accuracy
With a measurement error of just ±1mm, LDL-T ensures exact position control and feedback.
Fast Sampling Rate
Support for 30Hz real-time data acquisition enables responsive feedback for moving targets or rapid control systems.
Ultra-Compact Design
Measuring only 17 × 7 × 16.5 mm and weighing just 2g, this sensor fits seamlessly into tight enclosures and embedded systems.
Multiple Interfaces for Integration
Supports USB, TTL, RS232, RS485, and optional Bluetooth, compatible with most development boards and controllers.
Dual Wavelength Versions
Available in red laser for general use and green laser for high ambient light or reflective surfaces.
Versatile Platform Support
Easily integrates with Arduino, Raspberry Pi, ESP32, STM32, PLCs, and other platforms for industrial or academic development.

The LDL-T Laser Distance Sensor is ideal for a wide variety of use cases, including but not limited to:
Positioning of parts, object detection on conveyors, robotic arm calibration, CNC zero-point referencing.
Plant height monitoring, UAV altitude control, terrain mapping for precision farming.
Pallet detection, smart racking systems, automated guided vehicles (AGVs), distance-based sorting systems.
Vehicle profiling, height restriction detection, and proximity monitoring in toll systems or traffic management.
Ideal for engineers, academic research labs, and technical prototyping requiring a laser distance sensor module that balances size and performance.
Unmatched Accuracy in a Compact Package
Many high accuracy laser distance sensors on the market are large and costly. LDL-T delivers professional-grade accuracy in a miniature form factor at an affordable cost.
Engineered for System Integrators
With multiple interface options, stable output, and rich documentation, LDL-T is designed to integrate smoothly into larger systems, from industrial control to scientific instrumentation.
Reliable in Complex Environments
The dual laser option allows LDL-T to work across diverse materials and surfaces — including dark, bright, or semi-reflective targets — under strong sunlight or indoor lighting.
Stable and Continuous Output
The phase-shift ranging principle ensures repeatability and noise immunity, essential for high-reliability applications.
