Overview

Yunshis MVR3EC is a range LiDAR module for the MVR 3 series, using TOF (Time of Flight) technology with a 940 nm light source. It is designed to provide distance measurement from 0.3 to 30 meters (indoor and outdoor), with compensation for temperature, ambient light, and linearity to support stable ranging in different environments. The module provides UART output in HEX and ASCII data formats.

Key Features

  • Measuring range: 0.3 to 30 m (90% reflective whiteboard reference)
  • Measuring frequency: 10 to 200 Hz; adjustable 10/20/50/100/200 Hz (auto-measurement)
  • Field of view (full angle): 1.4 degree
  • Settable distance threshold for IO high/low control (TTL 3.3 V)
  • Small size: 31 x 18 x 19 mm; weight: 7 g
  • Note: maximum measurement speed is related to exposure time

Applications

  • Humanoid robots
  • Robotic arms
  • Exoskeletons
  • Quadruped robots
  • AGV vehicles
  • ARU robots
  • Drone obstacle avoidance and altitude control
  • Robot obstacle avoidance
  • Distance measuring instrument
  • Security monitoring

Notes on Field of View

The module uses infrared TOF technology: it calculates relative distance by emitting modulated infrared light signals and processing the reflected return at the receiving sensor. The optical design FOV of the detection area is 1.4°. Example: the area projected at a distance of 5 meters is 12 x 12 centimeters. If multiple objects are within the FOV range, the calculated distance may be affected.
