Introduction to 5V IR LED

5V IR LED is a type of semiconductor device that emits infrared light when an electric current passes through it. The "5V" in its name refers to the voltage required to operate the LED, which is typically 5 volts. These LEDs are available in different colors, with the most common being red, but they can also emit light in other wavelengths, such as near-infrared or far-infrared.

History of 5V IR LED

The concept of the light-emitting diode (LED) was first proposed by Oleg Vladimirovich Losev in 1927. However, it was not until the 1960s that the first practical LED was developed by Nick Holonyak Jr. at General Electric. Since then, the technology has evolved significantly, and 5V IR LED has become a popular choice for various applications.
