LamaPLC distance measurement: M01 - V0.4 Laser ranging sensor

A laser ranging sensor is a device that uses a focused beam of laser light to precisely measure distances to objects by detecting the reflected light. These sensors operate on various principles, most commonly Time-of-Flight (ToF) or triangulation, and are known for their high accuracy, fast response times, and ability to function in diverse industrial and commercial applications, from automation and robotics to surveying and quality control.
