Infrared (IR) is a type of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of microwaves. It is invisible to the human eye, but can be detected by electronic devices. Laptops can be equipped with infrared sensors, which allow them to communicate with other devices using infrared signals. This technology is often used for remote controls, but can also be used for other purposes, such as file sharing and data transfer.
There are a few different ways to check if your laptop has an infrared sensor. One way is to look for a small, black window on the front of your laptop. This window is usually located near the top of the screen. If you see this window, it is likely that your laptop has an infrared sensor.
