Description

The LightWare SF45/B (50 m) is a Class 1M eye-safe scanning microLiDAR sensor utilizing a 905 nm laser for precise distance measurement. Its oscillating mirror design enables a highly configurable horizontal field of view, adjustable from a few degrees up to 320°, making it adaptable for complex spatial sensing tasks. The sensor outputs detailed point cloud data, supporting nearest and farthest surface detection algorithms.

Engineered for integration in size and weight-critical systems, the SF45/B operates from a 5.0V to 5.5V DC supply and features robust serial (UART) and I2C digital interfaces, with 5V tolerance for easy connection to common microcontrollers and single-board computers. Its IP42 rating provides protection against limited dust ingress and water spray, supporting reliable operation in varied indoor and outdoor environments for robotics and unmanned vehicle platforms.

Key Features

  • High-performance scanning LiDAR with 0.2 m to 50 m measurement range.
  • Configurable 320° horizontal scanning field of view for adaptive sensing.
  • High data output up to 5000 measurements per second for real-time navigation.
  • Eye-safe Class 1M laser product (905 nm wavelength) for operational safety.
  • Multiple protocol support: Native USB, Serial UART, and I2C communication.
  • Compact, lightweight aluminum housing (59 g) for UAV and mobile robot integration.
  • Internal status monitoring for system health and diagnostic reporting.
  • Robust performance across varying lighting and environmental conditions.

Applications

  • Obstacle detection and avoidance for unmanned aerial vehicles (UAVs) and ground robots (UGVs).
  • Simultaneous Localization and Mapping (SLAM) and position-hold for autonomous navigation systems.
  • Proximity sensing and terrain following in robotic exploration and IoT sensor networks.
  • Industrial automation for presence detection and volumetric scanning in confined spaces.

Frequently Asked Questions

What is the field of view and how is it configured on the SF45/B sensor?

The SF45/B features a configurable horizontal field of view (FoV) that can be adjusted from a narrow beam to a wide 320° scan. Configuration is performed via the serial UART or I2C command interface using LightWare's provided software or API libraries, allowing you to tailor the scanning angle to your specific application, such as focused forward sensing or broad environmental scanning.

What are the available communication interfaces and their logic levels?

The sensor provides three primary interfaces: a native USB port for direct PC connection, a serial UART (TX/RX), and an I2C bus. The UART and I2C pins operate at 3.3V TTL logic levels but are 5V tolerant, allowing safe connection to both 3.3V and 5V microcontroller systems like Arduino, Raspberry Pi, and Pixhawk flight controllers without requiring a logic level shifter.

Is the SF45/B suitable for outdoor use and what are its environmental limits?

Yes, the SF45/B is designed for both indoor and outdoor operation. It has an operating temperature range of -10°C to +50°C and an IP42 ingress protection rating, which protects against limited dust ingress and water spray from above. Its 905 nm laser and sensing algorithm are tolerant to changes in ambient lighting, making it reliable in varying outdoor conditions for drone and robotic applications.

How do I integrate the SF45/B with autopilot systems like ArduPilot or ROS?

Integration is supported through dedicated drivers and libraries. For ArduPilot, you can connect the sensor's UART output to a telemetry or serial port on the flight controller and select the LightWare LiDAR driver within the ground station software. For ROS (Robot Operating System), LightWare provides a ROS package that publishes sensor data as standard LaserScan messages, enabling immediate use with navigation stacks like move_base for SLAM and obstacle avoidance.
