Third in a series of infrared (IR) LEDs, the OD-850L liquid-phase epitaxially-grown gallium aluminum arsenide (GaAlAs) IR emitters feature a medium emission angle for optimum coverage. Third in a ...
Ennostar and Taiwan Asia Semiconductor (TAS, formerly Opto Tech) are developing short-wavelength (over 1,000nm) infrared (IR) LED devices for use in biosensing including heart rates, SpO2, blood ...
In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...
