Description

The SF20/C R19.1 microLiDAR operates on the time-of-flight (ToF) principle, emitting laser pulses and measuring the time for the reflection to return, enabling precise distance calculation. Its single-beam design provides reliable, direct ranging data critical for navigation, obstacle avoidance, and altitude hold in dynamic applications.

Engineered for demanding environments, the sensor operates within a -10°C to +50°C temperature range and features a shielded 5-wire cable (32 AWG) for robust signal integrity. The unit’s high-speed data output and configurable measurement rate allow for real-time control loop integration in autonomous systems.

Key Features

  • Precise Laser Time-of-Flight (ToF) measurement with 1 cm resolution.
  • Wide, configurable measurement update rate from 48 Hz to 5 kHz for flexible system design.
  • Dual-interface flexibility with Serial UART and selectable I2C communication.
  • Compact, ruggedized housing with an IP65-rated front face for environmental durability.
  • Low power consumption, operating from a 4.5V to 5.5V DC supply with typical 100 mA current draw.
  • Pre-configured for major autopilot platforms (PX4, ArduPilot) and programmable via dedicated LightWare Studio software.
  • High-value build optimized for performance-to-size ratio in space-constrained OEM applications.

Applications

  • Unmanned Aerial Vehicle (UAV) altitude sensing and terrain following for autonomous flight control.
  • Robotics navigation and obstacle detection for mobile robots and automated guided vehicles (AGVs).
  • Industrial automation for precise non-contact level monitoring, positioning, and bin picking systems.
  • Research and development platforms for prototyping autonomous vehicle perception and SLAM algorithms.
  • Marine and agricultural equipment for height-above-ground measurement and implement control.

Frequently Asked Questions

What are the power requirements for the SF20/C microLiDAR?

The sensor requires a DC supply voltage between 4.5V and 5.5V, with a typical operating current of 100 mA. Ensure your power source can provide stable voltage within this range to guarantee accurate sensor performance and communication integrity.

How do I communicate with the sensor using I2C?

The SF20/C uses a fixed I2C address of 0x66 (hexadecimal) or 102 (decimal). It operates at 3.3V logic levels but is 5V tolerant on the communication lines. Connect the SDA and SCL pins to your microcontroller, ensuring you use appropriate logic level shifting if your host system operates at 5V.

What is the difference between the Serial and I2C interfaces?

The Serial UART interface provides a straightforward, continuous stream of distance data at 115200 baud, ideal for simple readouts. The I2C interface allows for multi-sensor bus operation and more advanced configuration, including setting the update rate and reading multiple data fields. You can select the active interface via command or physical configuration.

Is the SF20/C sensor suitable for outdoor use?

Yes, the front sensing face of the unit is rated IP65, making it protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for outdoor applications on drones or robots, though the main body and cable connections should be appropriately protected from the elements.

How do I configure the sensor and change settings like the update rate?

Advanced configuration, including setting the measurement update rate (from 48 Hz to 5 kHz), I2C address, and output format, is performed by sending specific command strings over the Serial or I2C interface. LightWare provides documentation and a configuration utility called LightWare Studio for Windows to simplify this process.
