infrared remote
Wireless device controller
An infrared remote is a handheld device that controls electronics by transmitting invisible light signals.
Television remotes are the most common type—you point them at the TV, press a button, and an infrared beam carries the command to a sensor on the device.
The technology requires line of sight; walls and obstacles block the signal.
