TV remotes still use infrared because it’s cheap, universal, and reliable. Remotes often use IR for basic functions and ...

We've grown a little spoiled. At some point during the progression of televisions and media devices, remote controls went from infrared sensors that required a direct line-of-sight between the ...

Turn on your Samsung TV using the power button on the TV or an already paired remote. Find the remote control sensor on the TV—it’s typically on the lower right side but may be at the bottom ...

In their experiment, the researchers used the dual-based IR remote sensing system to observe the spectral curves of the sun and airplanes in flight from distances up to 6 kilometers (4 miles).

Researchers have developed a smart sensor for DARPA that’s capable of identifying infrared -- without having to have its own power source.
