Laser Measuring Range Modules for OEM and Embedded Solutions

Laser Measuring Range Modules

Laser measuring range modules are becoming a cornerstone of modern embedded systems, industrial automation, robotics, UAVs, and smart logística. Meskernel, a leading Chinese manufacturer, offers a mature, high-precision product line that supports a wide array of applications — with the flexibility, accuracy, and customization that OEM developers demand.

1. Structure of Meskernel Laser Measuring Range Modules

Let’s break down the internal design of Meskernel’s laser measuring range modules, based on our publicly available technical architecture.

  • Princípio de medição
    Meskernel uses advanced phase-shift iToF (indireto Tempo de voo) technology for many of its sensors. By modulating the laser and analyzing the phase difference between transmitted and received signals, very high precision is achieved.
  • Laser & Optics
    • Wavelengths: Meskernel offers red laser (e.g., 620–690 nm) for certain modules, and also green (520 nm) for long-range and analog-output sensors.
    • Class safety: e.g., our 200 m module uses a Classe I green laser.
    • Optics design: tailored to deliver a stable beam and reliable reflection even under variable environmental reflection conditions.
  • Receiver / Signal Processing
    High-sensitivity photodiodes and signal processing board to filter ambient noise, correct for phase drift, and provide stable distance output.
  • Control/Processing Board
    Onboard MCU / DSP handles:
    1. Phase calculation (in iToF)
    2. Measurement filtering
    3. Mode switching (single-shot, continuous, high-speed)
    4. Communication over multiple protocols
    5. Calibration and compensation for temperature, reflectivity, ambient light
  • Mechanical / Power Design
    • Many Meskernel modules are extremely compact: e.g., our LDL-T 1 mm-accuracy module is as small as ~17.5 × 17.1 × 7.1 mm, weight only ~2 g.
    • Low power consumption to support battery-powered / embedded solutions.
    • Optional ruggedization / IP protection for harsh industrial environments.

2. Integration Flexibility — Interfaces Offered by Meskernel

One of Meskernel’s competitive advantages is how flexible our Laser measuring range modules are in terms of communication protocols and integration.

  • UART / TTL:
    Many of Laser measuring range modules (LDL-series) support UART / TTL interfaces, ideal for microcontroladores (e.g., STM32, Arduino) and embedded devices.
  • RS-232 / RS-485:
    For industrial-grade integration, Meskernel supports RS-232 and RS-485, meaning long-distance, high-noise environments like factories, AGVs, and PLC-based systems pode use our modules reliably.
  • USB:
    Some long-range or analog-output modules support USB for easy interfacing with PCs, measurement software, or data logging.
  • Analógico Output (4–20 mA / Voltage):
    Meskernel also provides distância do laser sensors with analog output. For example, our 200 m Class I green laser module supports current-loop output (4–20 mA) or voltage output, useful for industrial control systems.

This broad interface portfolio makes Meskernel laser measuring range modules highly deployable: from embedded robotics to industrial automation, to analog control loops.

3. OEM / ODM Customization Options — Why Meskernel Excels

Meskernel is not just a mass-product supplier; We emphasize OEM / ODM flexibility

  • Range & Accuracy Customization
    Our sensors already cover very wide ranges: from a few centimeters (e.g., 0.03 m) up to 5000 m for our long-range Sensores TOF.
    We support very tight accuracy tolerances — many models are ±1 mm.
    For special projects, Meskernel can adjust blind zone, reflection compensation, and environmental performance (e.g., for bright sunlight).
  • Interface / Protocol Customization
    We can support custom communication protocols, tailored packet formats, or mixed analog/digital outputs. OEM customers often request custom serial command sets.
  • Mechanical & Optical Design
    Options to customize housing (e.g., with IP rating), beam divergence, optics, and mounting footprints. This is especially useful for embedded devices, UAVs, or rugged industrial machines.
  • Firmware Customization
    Meskernel offers customization for measurement mode, filtering, calibration, sampling frequency, and even custom algorithms (e.g., to handle specific target materials or reflectivities).
  • Long-Term Collaboration
    Our experience in OEM / ODM projects: with 20+ years of R&D, 125+ patents, and a strong IP portfolio.

4. Example Integration: Meskernel Laser Range Modules in a UAV (Using Meskernel Products)

Here is a more concrete example using Meskernel laser measuring range modules in a UAV system, leveraging our real products:

  • Use LDL-S (Meskernel’s newly launched 1 mm-accuracy sensor) for altitude / ground tracking:
    • LDL-S range: 0.03 m to ~80 m according to our press release.
    • Very lightweight (module size ~17 mm, weight ~2 g), making it ideal for small UAVs.
    • Interfaces: UART or RS-232/485, so it can integrate directly into common flight controllers.
    • Modes: single-shot, continuous, different speed modes — useful to balance responsiveness and power.
  • Alternatively, use a long-range TOF sensor (Meskernel offers sensors up to 5000 m) for specialized UAV missions (e.g., high-altitude mapping or terrain-following in large areas).
    • These long-range sensors are particularly useful for topografia, mapping, or LiDAR-like applications.
    • Data from the module can be output over USB or serial and streamed into mapping or navigation software.
  • For power-sensitive UAVs, the compact LDL-T or LDL-S modules are useful: low standby current, small physical footprint, minimal weight.
  • Calibration workflow: when integrated, use Meskernel’s firmware features to calibrate for the reflectivity of ground surfaces (grass, soil, water, rooftops) so that the distance measurements remain stable and accurate in flight.
  • Flight controller integration: Use the sensor’s UART output to feed real-time altitude or height-above-ground data into the flight controller’s control loop — improving hover stability, landing precision, and desvio de obstáculos.
