Infrared light is in a wavelength that is just past the visible light spectrum detectable by the human eye. This makes infrared transmission and detection a great way to remedy an issue where visible light might interfere with the operation of a circuit. With infrared light emitting diodes we can make devices such a remote controls, communications systems, and alarm circuits. In this section you will find an assortment of IR LEDs that would make a great addition to the component list for your next infrared project.
