I want to make a universal remote for air conditioners but can not get a dataset containing ir hex or any codes to map for the same. can someone suggest me where can i find them.

I would doubt that there is any such repository. Who would set it up? Who would maintain it? How would they even know that they need to get the codes for the Model 101 from Bob's Air Conditioner Manufacturing and All Night Video Rental?

 

Many, perhaps most, air conditioners don't support remote control by IR.

Logitech's remotes can control a huge variety of devices and I'd be surprised if air conditioners are not included. I have no idea how their database is managed but it's vast.

 

I was about to say the same as WBahn myself actually, but I goggled it, and there are (of cause) apps to convert your phone into a universal remote control with a video showing someone choosing which AC unit they want to have control over!!

I doubt they would have the codes for ALL air conditioning units (which is what the TS is looking for), and I doubt you can download the codes to put into your own universal remote design (which is what the TS is looking to do). You could, potentially, write a program to essentially siphon the information from their site for the units that they do have the codes for, however.

But it also brings up the question of what the point would be. Why make a universal remote when you can make or buy a simple widget to plug into your phones headset jack and download an app and turn it into a universal remote instead?

Shifting gears -- I hate those kinds of videos. They pretend to show you how to do something without showing you a damn thing when all is said and done. Presumably those are two IR LEDs. Why two? Why the need to sand them down? Why don't you need the ground lead? Which jack lead goes to which LED lead?

Furthermore, the video could be pure bull. Imagine how easy it would be to fake that.

I was initially going to say that I have absolutely no reason to question the claims implied in the video, but actually I do. A few in fact.

1) I believe nearly all IR remotes are modulated at somewhere around 40 kHz (33 kHz to as high as 60 kHz).
2) Audio output is in the rang of 20 Hz to 20 kHz. What is the actual frequency that a typical smartphone headphone output can deliver?
3) An IR LED typically requires 1.5 V to 1.9 V forward voltage. Can a headphone jack deliver that?

It's conceivable that the reason for two LEDs is to put them back to back and essentially double the frequency by ping ponging them. That could get you up into the frequency range of most IR protocols.

 

for all of the air conditioners,it's impossible somehow.maybe just a desperate try to find libraries of zazaremote projects and similar ones .
but manually you can sniff codes of a certain AC and retransmit them by this arduino library : IRRemoteControl
note that remote control of any air conditioners,contains necessary datas of main device like Temp,fan speed,etc in IR signal that makes it difficault to decode the signals of various AC remotes.

 

Such repositories are Thier for TV and other it devices except air conditioner , wondering if I can find any one having codes of ac too.

I doubt it. People interact with air conditioners very differently than TVs and related devices. Just consider how many button presses you make a day for those other devices versus how many you make a year for your air conditioner. So there's naturally a higher demand for a universal remote that can consolidate and/or replace all of those other remotes.

 

The market opportunity is probably an OEM module that adds smart control of A/C controls compatible with Homekit and the other smart home standards. This would enable the manufacturers to offer smart-home compatible A/C units that you could control with your phone from anywhere. They likely don't want to be in the business of making such a device themselves and would prefer to buy them.
