905nm Laser Rangefinder Module 1000m SFA1000B

Selling Points

• Exceptional Long-Range Performance: This laser rangefinder achieves a maximum measurement range of ≥1000m (under optimal conditions: large target, visibility ≥10km, humidity ≤60%, target reflection coefficient 0.3), outperforming many compact models for long-distance detection needs.
• Industry-Leading Precision: With a measurement accuracy of ≤±1m (for distances ≤300m) and ≤±2m (for distances ＞300m), plus a 99% measurement success rate and ≤1% false alarm rate, the SFA1000B laser rangefinder ensures trustworthy data for critical decision-making.
• Ultra-Compact & Lightweight Design: Weighing ≤10g and measuring just ≤26mm×25mm×13.5mm, this mini laser rangefinder integrates seamlessly into devices like drones, security cameras, or handheld tools—no bulky hardware to hinder mobility.
• Wide Environmental Adaptability: Operable in temperatures from -20℃ to 60℃ and humidity levels below 80%, the SFA1000B laser rangefinder maintains stability in harsh conditions, from cold outdoor winters to warm industrial settings.
• Low Power Consumption: With a standby power consumption of ≤0.6W and operating power consumption of ≤0.8W, it extends battery life for portable applications—ideal for fieldwork or remote operations.
• Robust Anti-Interference Design: Power ground, communication ground, and structural ground are fully isolated, reducing electrical noise and ensuring consistent performance for the laser rangefinder in complex electronic systems.

Key Functions

• Dual Measurement Modes:
  • Single-shot measurement: Triggered via TTL serial commands, it delivers one-time accurate distance data for targeted checks (e.g., construction site surveys).
  • Continuous measurement: Supports selectable frequencies (1Hz, 2Hz, 5Hz) to capture real-time distance changes—perfect for dynamic tasks like UAV altitude tracking or moving target monitoring.
• Axis Calibration Mode: A dedicated calibration function (activated via command) ensures the laser rangefinder’s optical axis aligns with external devices (e.g., cameras), maintaining precision in integrated systems.
• Stable Data Transmission: Communicates via UART-TTL (3.3V) with a baud rate of 115200bps, enabling fast, error-free data transfer to upper-level devices (e.g., microcontrollers, laptops) for analysis or storage.
• Easy Shutdown Control: A simple stop-measurement command halts operations instantly, protecting the laser rangefinder’s components and conserving power when not in use.

Application Areas

• Outdoor & Adventure: Trusted by hunters, hikers, and campers for navigation, target ranging, and terrain assessment—its compact size fits easily in backpacks.
• Industrial Automation: Integrated into robotic arms, assembly lines, and material handling systems to monitor distances between components, ensuring precise manufacturing processes.
• Security & Surveillance: Enhances perimeter protection systems, drones, and security cameras by providing real-time distance data for threat detection or object tracking.
• Construction & Surveying: Used in land surveying, building inspections, and infrastructure projects to measure distances between structures, reducing human error in calculations.
• Aerospace & UAVs: Compatible with unmanned aerial vehicles (UAVs) for altitude measurement, obstacle avoidance, and target locking—critical for commercial or military drone operations.
• Marine & Boating: Assists sailors and boat operators in docking, navigation, and obstacle detection, ensuring safe travel in coastal or open-water environments.
