🤔 How it works …….. ⁉
🤔 Have You Ever Wondered.. How does a remote control work? What types of signals do remote controls emit?*
Today, remote control devices are usually based upon one of two main types of technology: infrared (IR) technology or radio frequency (RF) technology. When it comes to televisions and home theater devices, the dominant technology tends to be infrared. An IR remote (also called a transmitter) uses light to carry signals from the remote to the device it controls. These codes represent commands, such as power on, volume up, or channel down.
Once the signal is decoded, the microprocessor executes the commands. IR remotes use LED lights to transmit their infrared signals. This results in a few limitations of the technology. Since light is used to transmit the signal, IR remotes require line-of-sight, which means you need an open path between the transmitter and receiver
Radio-frequency remotes work in a similar way. Instead of using infrared light, though, they transmit binary codes to a receiver via radio waves. RF remotes can work at distances of 100 feet or more. This makes them useful in applications such as garage door openers and car alarms. wireless internet and cell phones both use radio signals.
