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.

Build a light-activated switch using LDR that lets you control home appliances using your mobile phone's torch.

Detect clog automatically, This is an independent laser motion sensor to sense filament clog ... The usage is almost the same as the switch filament runout sensor. there are a lot of instruction on ...

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 ...

Ortel, the California-based supplier of optical communications components now owned by Photonics Foundries, says it has ...

Laser Surface Velocimeters (LSV) from Polytec are optical length and speed sensors that exceed the performance of conventional contact-based measurement techniques such as encoder wheels and provide ...

Abstract: A novel optical fiber grating sensor fabricated using femtosecond laser direct writing technology, integrating 45° and 81° tilted fiber gratings (TFGs), a chirped fiber Bragg grating (CFBG), ...

Abstract: A high-sensitivity optical fiber temperature sensor based on the vernier sampling of tunable laser was proposed. The sensor contains only one fiber Sagnac interferometer (FSI), and the ...

The latest and most convincing evidence is a pair of new photos that emerged over the weekend showing what purports to be a finalized, production Switch 2 ... the optical sensor on the underside ...
