With one of these sensors, you can add a 2D touch surface to anything. It’s like an invisible laser harp that can also sense distance. The intended purpose is fingertip detection, and that’s ...

With a sprinkling of hardware and software, he was able to get these cheap laser particle sensors working on his Raspberry Pi, and his work was ultimately incorporated upstream into Mycodo.

Researchers at the University of Mississippi have come up with a faster, more efficient method for detecting landmines – ...

The thickness of the material is detected based on the difference principle. Two laser triangulation sensors are installed on a stable frame and are placed opposite to each other, and they further ...
