Optical sensor working
WebMuch of the research and development work in optical DO sensors has centered on the oxygen sensitive dye found in the luminophore. Several luminescent compounds are suitable for the optical DO sensor application; they fall into three main classes: Polycyclic aromatic compounds. Platinum-based compounds. Ruthenium-based compounds. WebJun 16, 2024 · Optical sensors have many more uses beyond their use in PC mice. Among its utilities are photocopiers and document scanners, and also to detect the presence of moving objects. The latter are used for automatic photography and alarm systems, especially to detect the presence of animals in the wild.
