Description

The Meskernel PTFS-H utilizes advanced pulsed laser time-of-flight (ToF) technology to deliver stable and reliable distance measurements over extended ranges. Its high 500Hz measurement frequency enables rapid data capture for dynamic applications requiring real-time feedback. The sensor’s 905nm wavelength is invisible to the human eye and classified as Class-I, ensuring eye-safe operation in various environments.

Designed for seamless integration, the module operates on a 3.3V DC supply and outputs distance data via a TTL serial interface, which is easily converted to USB with the included adapter. Its robust construction and wide operating temperature range from 0°C to 50°C make it suitable for both indoor and outdoor use in automation, robotics, and unmanned aerial vehicle (UAV) navigation systems.

Key Features

  • Pulsed Laser Time-of-Flight Principle: Provides stable, long-range distance measurement with good ambient light immunity.
  • High-Speed Measurement: 500Hz output frequency allows for real-time object tracking and fast system response.
  • Eye-Safe Operation: Class-I 905nm invisible laser ensures user safety and compliance in diverse settings.
  • Low Power Consumption: Optimized for 3.3V systems with a typical power draw of 330mW, ideal for battery-powered applications.
  • Compact and Lightweight Design: Aluminum housing (43x35x21mm, 18g) enables easy mounting in space-constrained projects.
  • Wide Operating Temperature Range: Functions reliably from 0°C to 50°C, with storage from -30°C to 60°C.
  • Simple Serial Interface: TTL UART communication protocol is straightforward to interface with most microcontrollers and computers.

Frequently Asked Questions

What is the operating voltage range for the PTFS-H sensor, and can it tolerate 5V logic?

The PTFS-H operates strictly on a DC input voltage from 2.5V to 3.5V, with a typical value of 3.3V. Applying 5V to its power or data pins can damage the module. Its TTL serial output is also at 3.3V logic levels. When connecting to a 5V microcontroller, a logic level converter is required for safe communication.

How do I communicate with this sensor and read distance data?

The sensor communicates via a TTL-level UART (serial) interface. You connect the TX, RX, GND, and VCC pins to your host controller. The module outputs distance data in a predefined serial packet format at a configurable baud rate (default is typically 9600 or 115200 bps). The included USB-to-TTL adapter allows direct connection to a computer for testing and configuration.

What is the accuracy and performance in different lighting conditions?

The sensor has a stated accuracy of ±1 meter across its 3M to 100m range. As a pulsed laser time-of-flight sensor, it is generally more resistant to ambient light interference compared to continuous-wave or infrared sensors. However, performance can be affected by highly reflective or absorbent targets, as well as heavy fog or rain, which can scatter the laser pulse.

Is the 905nm laser safe for eyes, and are there any specific mounting considerations?

Yes, the laser is classified as Class-I, which is considered eye-safe under normal operating conditions, meaning no special laser safety precautions are required for users. For optimal performance, mount the sensor securely to minimize vibration, ensure the laser aperture is clean and unobstructed, and avoid pointing it directly at highly reflective surfaces at close range to prevent signal saturation.
