LDJ Long Range Laser Sensor: Advanced Measurement for Industrial and Engineering Applications
Introduction
The demand for precise and reliable distance measurement technology is growing rapidly across industries. The LDJ long range laser sensor is designed to meet this need with a measuring distance of up to 200 meters, accuracy of 2–3mm, and a high measurement frequency of up to 30Hz. Engineered for versatility, this sensor supports a variety of applications, from industrial automation and logistics systems to robotics navigation and structural monitoring.
Explore the LDJ Long Range Laser Sensor and learn how it can provide reliable performance for high-precision distance measurement tasks.
Phase-Shift Measurement Principle for High Accuracy
At the heart of the LDJ long range laser sensor is phase-shift measurement technology. This advanced method measures the phase difference between emitted and reflected laser beams, ensuring stable, repeatable, and highly accurate distance readings even in environments with changing reflectivity or interference light. Compared to conventional time-of-flight methods, phase-shift sensors deliver enhanced precision, especially for applications that demand fine tolerances and consistent results.
Red or Green Laser Options for Versatile Applications
The LDJ sensor series provides flexibility with two laser wavelength options:
- Red Laser (610–690nm) – An efficient and cost-effective choice for indoor environments and low to moderate ambient lighting conditions.
- Green Laser (510–550nm) – Offers higher visibility and better performance outdoors or in high-glare settings, making it ideal for challenging environments.
This dual-laser configuration allows users to select the optimal version based on their specific project needs, ensuring maximum performance and efficiency.
Flexible Connectivity and Platform Compatibility
Connectivity plays a crucial role in modern measurement systems, and the LDJ long distance laser sensor is built to integrate seamlessly. It supports multiple communication protocols, including Modbus, UART, RS232, RS485, and Bluetooth, making it suitable for integration with industrial controllers and data systems.
Additionally, it is compatible with development platforms such as Arduino, ESP32, and Raspberry Pi, enabling engineers, developers, and research teams to incorporate it into custom projects with ease.
