How to know the frequency of the IR remote control?

Question

Arduino

Good, habr.
There is a Sony TV, there is a remote control from it. How to find out the frequency of the remote control in order to choose an IR receiver for it?
I watched the documentation on TV, separately on the remote control, used Google, information 0. Only approximate data at the level of “maybe” and “most likely”.
How to accurately know its frequency in order to select the appropriate receiver?
Thanks in advance for your replies.

Answer 1

Build any LIRC receiver. 99% that your remote will work with it.

Answer 2

In general, all remotes plow according to the RC5 standard - radioparty.ru/index.php/device-pic/392-lesson-rc5

Answer 3

Here, according to this article, I made the recognition of signals from some kind of remote control, everything works.

Answer 4

Now all remotes operate in the same frequency range. The old range - these were such Waltham TVs, now there are no such remotes for a long time.

Answer 5

Let's first read the title of the topic "How to know the frequency of the IR remote control?".
This is exactly the query I googled.
And what do you answer?
- It will work on any receiver... -
The consoles are all the same...
- Everything works according to this scheme for me...
Well, let's complicate the task.
I have a laser tag gun that "shoots" IR signals.
VS1838 receives signals, but with distortion, since the frequency does not match.
So the question is: How to find out the frequency of the IR signal?
In general, a year later, I am ready to give an adequate, proven method.
Replace the frequency of the sent signal with an oscilloscope.
Personally, I used the simplest DSO138.
I connected the probes to the IR LEDs of the remote control, the oscilloscope switched to the signal display mode only when it was present (not a constant screen update).
When you press a button on the remote control DSO138 shows the shape and frequency of the signal.
It is this oscilloscope that operates at frequencies up to 200 MHz, but it is recommended to read signals up to 100 MHz.
Good luck to all!
