Meskernel LDK-60 Laser Distance Sensor Module, 60 m, ±2 mm, UART/TTL RS232 RS485 Bluetooth, 620–690 nm Class II

Overview

The Meskernel LDK-60 laser distance sensor module is a UART serial laser distance sensor designed for embedded development and measurement projects. This compact optical sensor uses laser phase measurement to deliver millimeter-level precision, making it suitable for ESP32, Arduino, and other MCU platforms via UART/TTL or optional RS232/RS485/Bluetooth interfaces. Typical uses include distance measurement and transmission in industrial automation, logistics, engineering surveying, and warehouse level gauging.

Specifications

Notes

• Under strong ambient light or very high/low target reflectivity, error may increase: ±1 mm + 50 PPM.
• Use a reflector for strong light environments or poor target reflectivity.
• Operating temperature of -10–50 °C can be customized.
• 8 Hz is only available in fast continuous measuring mode.

Applications

• Industrial automation: level/position measurement and conveyor alignment
• Engineering surveying: point-to-point distance mapping and layout
• Intelligent logistics and warehousing: navigation, sorting, and inventory level detection
• Robotics (e.g., robot vacuum): obstacle distance measurement and avoidance
