What is an IR receiver and how does it work?
An IR (infrared) receiver is an electronic device used to detect infrared signals emitted by a remote control. These signals are transmitted in the form of light waves that are invisible to the human eye. When you press a button on a remote, it sends a specific pattern of these waves, which the IR receiver interprets and translates into a command for the device it’s connected to, such as a television or audio system.
The core components of an IR receiver include a photodiode, which captures the infrared signals, and a decoder that interprets these signals into a binary format. This allows the device to understand various commands, such as turning on or off, changing channels, or adjusting the volume. Understanding how an IR receiver functions is crucial for successful setup and troubleshooting.
