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 ...
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 ...
Infrared LEDs have been around for over half a century and have been put to use in myriad applications since their development. Before we take a look at some of these uses, though, here are some fun ...
