Aninfraredlight-emittingdiode(LED) is a type of electronic device that emits infrared light not visible to the naked eye. An infrared (IR) LED operates like a regular LED, but may use different materials to produce infrared light. This infrared light may be used for a remote control, to t...
An infrared light-emitting diode (IRLED) is a special-purpose LED that emits infrared signals. Specifically, it is a semiconductor device that releases infrared rays when exposed to electrical current.

As noted earlier, a very weak visual stimulus exists even at 1100 nm; and IR-A is deeply penetrating into biological tissues and thus used in diagnostics and in skin treatments. The infrared B ranges between 1.4 μm (1400 nm) and 3.0 μm (middle infrared), and these wavelengths do not...

LDR (Light Dependent Resistor) as the name states is a special type of resistor that works on the photoconductivity principle means that resistance changes according to the intensity of light. Its resistance decreases with an increase in the intensity of light. It is often used as a light senso...
In the United States, more than 30,000 people are believed to be living with ALS, and an average of5,000 peoplein the U.S. are diagnosed with ALS each year, according to the Centers for Disease Control and Prevention. "ALS is a devastating illness," Dr. Sandeep Rana from Allegheny He...
