I would like to know if there is the possibility of developing a mobile application in Delphi XE5 or higher, where it could send Infrared (IR) signal to any receiver, for example a TV.

I think I get your idea, you want to make a kind of universal control for your home and operate it by cell phone.
If it is to sell the application, I suggest you make an infrared emitter that works with network and that you operate the same by Wifi phone, because most devices today do not have this hardware included.
But if it is for specific use this has already been done just search the Play Store you find several of them.
Regarding Delphi, I believe there is more literature and documentation for Java.
Take a look at this and look for more videos about it. https://www.youtube.com/watch?v=3lqEzpZeBwo
In the matter of Java I have:
Infrared transmitters
When running on a device that includes an infrared (IR) transmitter, you can now transmit IR signals using the Consumerirmanager Apis. To get an instance of Consumerirmanager, call getSystemService() with CONSUMER_IR_SERVICE as argument. You can then query supported IR frequencies from the device with getCarrierFrequencies() and transmit signals by passing your desired frequency and signal pattern with Transmit().
You should always check first if the device includes an IR transmitter by calling the hasIrEmitter() method, but if your application is only compatible with devices that have one, you should include an element in your manifest for "android.hardware.consumerir"( FEATURE_CONSUMER_IR ).

The Consumerirmanager class: https://developer.android.com/reference/android/hardware/ConsumerIrManager.html
I believe it only works on Kitkat but it’s not certain. link Kitkat: https://developer.android.com/about/versions/kitkat.html

Yes I want to make a universal control for my home, but unfortunately air conditioning for example does not come with wifi, so I can not control with my smartphone, I know there are already application in google play, but there are specific hardware that I manufacture with IR receiver, what I’m looking for is a component or DLL that I can use in Delphi to resolve my situation.

Then last year I had this same idea that you, I researched a lot, I found some interesting things even. but I came to the conclusion that it would be much easier to create an infrared emitter system with those diffusers (same presence sensor) and a WIFI or Bluetooth module and put one by commode. at the time I had quoted this, I think it would come out something around 10 more finish, so you can always issue IV to all the equipment of your house being in your room for example

I was just reading about the Apis, and it’s really only going to work with Kitkat, but it doesn’t matter.

I added a code I found on the net (I don’t know if it works) and a documentation from XDA devellopers

added other information and a source of inspiration for your project design

Since there is hardware dependency, you will need to know if the device has such a feature and if the operating system makes such an API available. Your question is very general.
– EProgrammerNotFound
It may even be generic, but responsive, I wonder if anyone has ever done any application in Delphi XE5+ that uses the IR sensor, whether there is already component or some library for the devices that contemplate this sensor.
