This compact 905nm laser rangefinder module (Φ23mm × 40mm, ≤18g) delivers high-precision distance measurement (10m–1200m) with ±1m accuracy, making it ideal for robotics, drones, and industrial automation. Its Class 1 eye-safe laser ensures user protection, while fast response (1–3Hz, ≤500ms startup) and ≥98% measurement reliability within 400m enhance real-time performance. The rugged design withstands extreme temperatures (-20°C to +55°C operation, -55°C to +65°C storage), ensuring durability in harsh environments. With low power consumption (≤1.5W) and a UART (TTL 3.3V) interface, it integrates seamlessly into smart sensors, AGVs, and surveying equipment. Whether for obstacle avoidance in autonomous systems, precision mapping, or industrial positioning, this module combines lightweight portability, military-grade resilience, and consistent accuracy for mission-critical applications.
