LDL-S USB Laser Distance Sensor – Fast, Accurate, and Ready for Integration
Precision, speed, and size are no longer trade-offs. The LDL-S USB Laser Distance Sensor delivers accurate measurements up to 80 meters in a compact and lightweight body, making it an ideal choice for developers and engineers working on tight-spaced or mobile applications. Measuring with 1mm accuracy and operating at up to 30Hz, this small laser distance sensor is built to support both dynamic motion systems and high-volume measurements.
The LDL-S supports USB connectivity for instant development access, and offers interface expansion to RS232, RS485, TTL, or even Bluetooth, depending on your design needs. It’s also available as a customizable OEM unit.
Built for integration into compact systems, the LDL-S features a rugged aluminum body with a precision glass lens, offering excellent heat dissipation, signal stability, and long-term durability. Its small size makes it ideal for use in robotics, smart devices, measurement tools, and automated sensing units.
The sensor supports both green (510–550nm) and red (610–690nm) laser light options. Green lasers improve outdoor visibility and are easier to track in bright light, while red lasers are more power-efficient and suitable for general environments.
At the heart of the LDL-S is a phase-shift measurement system that ensures high-frequency and high-accuracy distance evaluation. By analyzing the phase delay between emitted and reflected laser beams, the sensor maintains consistency even over longer distances or when targeting low-reflective surfaces.
The LDL-S is designed with flexibility in mind. It works seamlessly with mainstream electronics and development platforms:
Arduino and ESP32 for academic and hobbyist use
Raspberry Pi for project-based prototyping
Industrial PLCs for factory and automation integration
With broad interface support, the sensor can be deployed quickly across multiple industries and project types.
Industrial robotics: Precision positioning and path correction
Logistics and warehouse automation: Cargo height and space detection
Smart agriculture: Monitoring equipment movement and crop levels
Infrastructure inspection: Bridge height, tunnel clearance, and construction alignment
Unmanned systems: Obstacle detection and terrain tracking for drones and autonomous vehicles
