Description

The LightWare SF23/B microLiDAR® sensor utilizes a 905 nm infrared laser and time-of-flight (ToF) principles to deliver precise distance measurements from 0.2 to 50 meters. Its design prioritizes power efficiency, with an average current draw below 5 mA at a 1 Hz sampling rate, making it ideal for battery-powered and mobile systems.

Housed in a robust, compact enclosure, the sensor operates across a -20°C to 60°C temperature range and is certified as a Class 1 eye-safe device. The integrated Serial UART interface provides straightforward communication and control, allowing for easy configuration of update rates and integration into autonomous navigation, robotics, and industrial sensing systems.

Key Features

  • Extended Range Performance: Measures distances from 0.2 m to 50 m (up to 100 m on high-reflectivity targets), maintaining accuracy in direct sunlight.
  • Optimized Power Management: Exceptionally low average current consumption (<5 mA at 1 Hz) enables long-term operation in portable and UAV applications.
  • Eye-Safe Operation: Certified as a Class 1 laser product, ensuring user safety with no special handling requirements.
  • Robust Environmental Tolerance: Operates reliably across a wide -20°C to 60°C temperature range for diverse deployment scenarios.
  • Flexible Communication: Serial UART interface with 3.0V logic levels simplifies wiring and protocol integration with common microcontrollers and SBCs.
  • Configurable Update Rate: User-selectable sampling frequency from 1 to 20 readings per second to balance data freshness and power consumption.
  • Compact & Durable Build: Miniature 32 x 30 x 22 mm form factor with a ruggedized housing for vibration-resistant mounting.

Applications

  • Obstacle avoidance and terrain following for unmanned aerial vehicles (UAVs) and drones.
  • Precision altitude hold and landing systems for autonomous robotics.
  • Object detection and proximity sensing in automated guided vehicles (AGVs) and mobile robots.
  • Industrial inventory management and bin-level sensing using non-contact distance measurement.
  • Research and development platforms for SLAM (Simultaneous Localization and Mapping) and 3D scanning.

Frequently Asked Questions

What is the logic voltage level for the SF23/B's Serial UART interface?

The SF23/B microLiDAR sensor operates on 3.0V logic levels for its Serial UART (TX/RX), shutdown, and control pins. It is not 5V tolerant. When connecting to a 5V microcontroller like some Arduino boards, you must use a logic level converter or a voltage divider to avoid damaging the sensor.

How do I configure the sensor's update rate?

The update rate, from 1 to 20 readings per second (Hz), is configurable via specific serial commands sent over the UART interface. Refer to the official LightWare communication protocol documentation or use the provided LW Studio software for a graphical interface to adjust the sampling frequency and other parameters.

Is this sensor suitable for outdoor use in bright sunlight?

Yes, the SF23/B is designed to perform reliably in bright sunlight conditions. Its 905 nm infrared laser and advanced signal processing allow it to achieve its specified 0.2 to 50 m range even with high ambient light interference, making it well-suited for outdoor robotics and drone applications.

What is the typical power consumption of the SF23/B sensor?

Power consumption is highly efficient, averaging less than 5 mA when operating at the default 1 Hz update rate. Consumption will scale approximately linearly with the update rate. A dedicated shutdown pin is also provided to cut power completely when measurements are not required, further conserving energy in battery-sensitive designs.
