905nm Laser Rangefinder Module 1.5km SF-DYA1501A

The ​SF-DYA1501A is a high-accuracy, Class 1 laser rangefinder module designed for seamless integration into drones, robotics, and IoT systems. With a 1550nm eye-safe laser, it achieves ±0.1% accuracy over 2000m and weighs only 85g. Ruggedized for -30°C to +70°C operation, this low-power (1.2W) module supports RS485/CAN interfaces, making it ideal for industrial automation, precision agriculture, and security systems.

Top Selling Points

  • Ultra-Lightweight (85g) with IP67 protection
  • Plug-and-Play Integration via open-source SDK
  • Real-Time Data Output (10Hz refresh rate)
  • Energy Efficiency (0.05W standby power)

Applications:

  • Drone-based topographic mapping
  • Autonomous vehicle navigation
  • Smart warehouse inventory management
  • Solar farm maintenance monitoring
