Description

The TF-UW500 utilizes Time-of-Flight (ToF) laser ranging technology, optimized for the challenging optical properties of water. Its narrow beam and advanced signal processing algorithm filter out backscatter and ambient noise, delivering reliable distance data even in low-visibility or high-ambient-light underwater scenarios. The sensor’s robust design is built for integration into submersible platforms.

Communication is handled via a simple UART serial protocol at 3.3V TTL logic levels, providing real-time distance measurements at a 20Hz frame rate. The compact, low-power design features a 1.0mm-4P connector, making it ideal for space-constrained underwater vehicles, automated depth gauging, and structural inspection systems where precise, non-contact measurement is critical.

Key Features

  • Underwater-Optimized ToF LiDAR: Laser-based Time-of-Flight technology specifically calibrated for water's refractive index and attenuation.
  • High Precision & Stability: Delivers <3 cm accuracy with 1 mm resolution and <1 cm repeatability (1σ, 0.1-2m) for dependable data.
  • Narrow Beam & Light Immunity: Ultra-narrow <0.5° FOV and 100kLux ambient light resistance minimize interference from particles and sunlight.
  • Compact & Low-Power Build: Miniature 24 x 16 x ~10 mm form factor consumes <700 mA peak current at 5V DC.
  • Industrial-Grade Interface: UART serial output (3.3V TTL) with a durable 1.0mm-4P connector for reliable system integration.
  • Safety Certified: Complies with Class 1 laser safety standards (IEC/EN 60825-1) for eye-safe operation.

Applications

  • Underwater Robotics & ROVs: Precise obstacle avoidance, docking, and terrain following for autonomous underwater vehicles.
  • Marine Infrastructure Inspection: Non-contact measurement of hull clearances, pipeline standoff, or structural deformation.
  • Automated Depth Sounding: Integration into buoy-based or fixed-position systems for accurate water level and draft monitoring.
  • Aquaculture & Tank Monitoring: Measuring biomass density, net deformation, or water level in contained environments.
  • Scientific Instrumentation: Deployed on sensor packages for precise positioning relative to seabed or underwater structures.

Frequently Asked Questions

What is the communication protocol and how do I interface with the TF-UW500 sensor?

The TF-UW500 communicates via a UART serial interface at 3.3V TTL logic levels. You will need a UART-capable microcontroller (like an Arduino, Raspberry Pi, or STM32) and connect to its 1.0mm-4P connector following the pinout for power (5V, GND), TX, and RX. The sensor outputs real-time distance data packets at a configurable baud rate.

What are the power requirements for this underwater LiDAR sensor?

The sensor requires a stable 5V DC power supply and can draw a peak current of less than 700mA during operation. Ensure your power source can provide clean, regulated 5V power. The logic level for the UART data lines is 3.3V TTL, so ensure your host controller uses 3.3V logic or a level shifter is employed.

Is the TF-UW500 suitable for use in saltwater or other harsh environments?

While the TF-UW500 is designed for underwater operation, its standard housing may not be inherently rated for prolonged saltwater immersion or high pressure without additional protective encapsulation. For harsh marine environments, consult the manufacturer's specifications regarding housing material and consider protective measures or an appropriate pressure-rated enclosure for deep-SEA applications.

How does ambient light and water clarity affect the sensor's performance?

The sensor features high ambient light immunity up to 100,000 Lux, making it resistant to sunlight penetration. However, water clarity significantly impacts performance; high turbidity or suspended particles can scatter the laser beam, potentially reducing the maximum effective range. The narrow <0.5° FOV helps mitigate some of this interference for precise single-point measurement.
