WebNov 3, 2024 · How does a TV remote work physics? Light is reflected from a mirror at an angle equal to the angle that it hit the mirror. The front end of a remote control has a small light bulb. When you press a button on the remote, it sends out an infrared light signal. A detector on the TV gets these signals and tells the TV what you want it to do. WebKeyless remotes contain a short-range radio transmitter, and must be within a certain range, usually 5–20 meters, of the car to work. When a button is pushed, it sends a coded signal …

WebApr 25, 2014 · If it's line of sight, then a simple way would be to use an IR transmitter and IR detector. The transmitter can be an IR LED pulsed at the receivers frequency (use a microcontroller, 555 timer, PWM IC, etc for this) this will create a logic high at the receiver output which can be used to trigger your circuit. WebMar 22, 2024 · No universal remote, including Tivo, can control your Denon directly via RF. That's not in dispute. The signal must ultimately be IR (converted by an RF base station as you suggested, or some other RF-to-IR device). The Tivo remote transmits both RF and IR. There is no conversion necessary.
WebNov 10, 2005 · Some IR remotes can send out both IR and RF signals. The RF signals aren't meant to control RF devices (in fact, they can't control them). They're meant to extend the operating range of the IR remote control from about 30 feet to about 100 feet (give or take) and allow the signal to penetrate walls and glass cabinet enclosures.
