Description

This sensor employs advanced Direct Time-of-Flight (dTOF) technology, which calculates distance by measuring the precise round-trip time of a modulated laser pulse. This method provides superior accuracy and stability compared to traditional infrared or ultrasonic ranging, especially in varying light conditions. The module’s integrated signal processing ensures consistent performance across its full 0.1m to 50m range.

Engineered for demanding environments, the sensor’s optical system is designed to reject intense ambient light up to 100,000 lux, making it suitable for direct sunlight applications. Its 5V DC operation and digital communication protocols (UART/I2C) allow for straightforward connection to industrial PLCs, robotics controllers, and embedded development systems without requiring complex analog signal conditioning.

Key Features

  • High-Precision dTOF Core: Utilizes Direct Time-of-Flight laser technology for stable, accurate distance measurements independent of target color or reflectivity.
  • High-Speed Data Output: 100Hz update rate enables real-time tracking for fast-moving objects in automation and navigation systems.
  • Superior Ambient Light Immunity: Engineered optical filter and processing algorithm reliably operate under 100K LUX, ensuring performance in bright outdoor settings.
  • Multi-Protocol Communication: Offers selectable UART (serial) and I2C digital interfaces, plus a GPIO trigger mode for maximum integration flexibility.
  • Compact & Durable Construction: Features a robust PCB design with a protective housing, optimized for integration into drones, robots, and industrial equipment.
  • Wide Operating Range: Measures from 0.1 meters up to 50 meters, covering both near-field and long-range applications.
  • Simple 5V Power Supply: Operates from a standard 5.0V DC source, compatible with most microcontroller and logic-level power systems.

Applications

  • Drone Navigation & Altitude Hold: Provides precise ground distance for autonomous landing, terrain following, and obstacle avoidance in UAVs.
  • Industrial Automation & Robotics: Enables accurate object detection, bin picking, and positioning for robotic arms and AGVs (Automated Guided Vehicles).
  • Outdoor 3D Scanning & Mapping: Serves as a long-range measurement node for terrestrial LiDAR scanning and topographic survey systems.
  • Construction & Logistics: Measures stockpile volumes, vehicle positioning, and crane hook height in bright, outdoor industrial yards.
  • Smart Traffic & Parking Systems: Detects vehicle presence and measures queue lengths at toll gates or parking lot entrances.

Frequently Asked Questions

What is the operating voltage and how do I power this TOF sensor?

The sensor operates at a standard 5.0V DC. You can power it directly from the 5V pin of an Arduino, Raspberry Pi (via a GPIO header pin or external regulator), or any other stable 5V power supply. Ensure your power source can provide sufficient current for stable operation.

What communication interfaces are supported and how do I select them?

The module supports UART (serial), I2C, and a simple GPIO trigger mode. The interface is typically selected via physical configuration pins (jumpers or solder pads) on the PCB or by sending specific configuration commands over the default UART interface. Consult the product datasheet for the precise selection method.

How does the 100K LUX sunlight resistance work, and is calibration needed for outdoor use?

The sensor uses a specialized optical filter and a dTOF processing algorithm that discriminates the modulated laser pulse from broad-spectrum ambient light. No user calibration is typically required for different light conditions. Its performance is inherent to the design, ensuring reliable measurements even in direct sunlight.

What is the minimum and maximum measurable distance?

The sensor has a functional range from 0.1 meters (10 cm) up to a maximum of 50 meters. Measurements closer than 0.1m may be unreliable. For optimal accuracy, ensure the target is within this specified range and has sufficient reflectivity.

Is this sensor suitable for measuring moving targets?

Yes, the high 100Hz refresh rate makes it well-suited for tracking moving objects. It can provide up to 100 distance readings per second, allowing for real-time position tracking in applications like drone navigation, sports tracking, or conveyor belt monitoring.
