LIRC (Linux Infrared remote control) is an open source package that allows users to receive and send infrared signals with a Linux-based computer system. There is a Microsoft Windows equivalent of LIRC called WinLIRC. With LIRC and an IR receiver the user can control their computer with almost any infrared remote control (e.g. a TV remote control).
Consumer IR, consumer infrared, or CIR is a class of devices employing the infrared portion of the electromagnetic spectrum for wireless communications. [citation needed] CIR ports are commonly found in consumer electronics devices such as television remote controls, PDAs, laptops, computers, and video game controllers.
The first would be to capture the IR bitstream from the handset of newer Philips products, such as DVD players and analyze them to see what system number is used. The other would be to use the popular Philips Pronto series of programmable remote controls. These can be programmed to operate Philips components using the RC-5 protocol.
IR blaster with standard 3.5 mm plug IR blaster attached to a cable TV tuner. An infrared blaster (IR blaster) is a device that relays commands from a remote control to one or more devices that require infra-red remote control. For instance, it may also allow radio-frequency-based (RF) remotes (including those using Bluetooth) to control infra ...
Most of these have an IR receiver, picking up the IR signal and relaying it via radio waves to the remote part, which has an IR transmitter mimicking the original IR control. Infrared receivers also tend to have a more or less limited operating angle, which mainly depends on the optical characteristics of the phototransistor. However, it is ...
In addition to controlling the Apple TV itself, the Siri Remote can learn the IR codes to control the volume of a TV, sound bar, or receiver. On September 12, 2017, along with the announcement of the Apple TV 4K, Apple announced an updated Siri Remote with a raised white border around the menu button and additional motion input for apps.
Optical heterodyne detection is a method of extracting information encoded as modulation of the phase, frequency or both of electromagnetic radiation in the wavelength band of visible or infrared light. The light signal is compared with standard or reference light from a "local oscillator" (LO) that would have a fixed offset in frequency and ...
Conceptual through-beam system to detect unauthorized access to a secure door. If the beam is interrupted, the detector triggers an alarm. A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver.
