Learn About IR Repeaters: Controlling Hidden A/V Components

    https://www.cmple.com/learn/learn-about-ir-repeaters
    The repeater works in three stages. First, it receives the infrared signal from a remote control, and then converts the signal into an electrical one which can be transmitted either through a wired connection, or by radio frequency signals sent through all of your home theater or A/V wiring.

    In order to extend the range of a typical infrared remote control beyond line of sight, it is possible to combine an IR transmitter and receiver with another component. A hardwired extender unit uses a transmitter and receiver that are connected by a physical wire.

Infrared Remote Controls: The Process - How Remote ...

    https://electronics.howstuffworks.com/remote-control2.htm
    When the infrared receiver on the TV picks up the signal from the remote and verifies from the address code that it's supposed to carry out this command, it converts the light pulses back into the electrical signal for 001 0010. It then passes this signal to the microprocessor, which goes about increasing the volume.

How does Infrared Work? (with pictures) - Info Bloom

    https://www.easytechjunkie.com/how-does-infrared-work.htm
    Sofree Infrared ( IR) light is a wavelength of energy that is invisible to the human eye. The most common source of this energy is heat; objects can have their relative temperatures measured by how much of this energy they give off.

How does IR spectroscopy work? + Example - Socratic.org

    https://socratic.org/questions/how-does-ir-spectroscopy-work
    Jul 7, 2017 Infrared (IR) spectroscopy uses infrared radiation to excite the molecules of a compound and generates an infrared spectrum of the energy absorbed by a molecule as a function of the frequency or wavelength of light. Different types of bonds respond to the IR radiation differently.
