Yes they are not great receivers & only cost a few cents.

For higher quality go with Vishay.

TSOP34438 or other TSOPxxx38 should work fine.

They would need a lot of internal memory to capture the raw modulated signal. So I expect they reduce it to timings & carrier frequency. From investigations I have done in the past by looking at captured signals in EEPROM on these remotes....they seem to have some clever recognition algorithms w...

Thanks for sharing. It is most likely some dedicated internal circuitry of the main IC in the remote. However, check out our blog post to see how it can be done using simple components. https://www.analysir.com/blog/2014/05/28/poor-makers-infrared-receiver-2/ They are probably doing something similar.

Unfortunaetly not.

The focus here is on IR for remote control....not thermal.

I am travelling at present with limited time available, so here is a quick response: - you will only get 1 IR led in series (becasue 2x1.8V = 3.6V)....unless you create parallel driver circuits. - Don't think about 1A current. On USB power devices I would send a max of 300mA "peak" current...

There are about 5 laser tag protocols supported. Usually we will add new ones - if not too complicated.

Supporte means oyu get the binary/hex values. It is up to userers to reverse engineer protocols further

This is most likely because you are getting a poor capture of the signal. AnalysIR has a feature that can work-around this. Simply increase the "tolerance" slider for that channel until; it is decoded. However, it is always better to get a good capture in the first place. To help with this...

Not aware of any available database for AC signals (free or paid). Your best option is to buy a universal AC remote from aliexpress and capture the signals. We alsways suggest users just capture the most common signals they use and store them for later replay. It is also paoosible to reverse enginee...

You will need a 455kHz receiver (very rare) to decode the signals, before you can send them. However, I believe many B&O systems can also accept more normal signals - you will need to read up on that. Finally, if you can find info online about your specific signals it may be possible to generate...

First of all the signal you posted are the RAW signals, on first look. I uploaded them toour AnalysIR app and they look like the following (essentially the same signal) 2024-08-14 17_12_59_ScreenShot.jpg However, they might have been truncated by you capture system. I cannot offer anymore unless you...
