The IT Receiver sensor (SM0038) is receiving signals and reporting values even when not pressing any button in the remote.

I'm trying to control an air-conditioner using Arduino UNO. To receive IR signals from the remote, I'm using SM0038 IR receiver to receive signals form the remote and give hex codes for the ON and OFF command. And once I receive an array of codes for both, I'll give them in another program and give temperature conditions accordingly to invoke them to switch the AC on and off.

But, my IR receiver is continuously receiving signals even while not pressing any button. And the codes which I got by pressing the buttons keep changing each time. Those codes when given in another program does not replay to the AC to switch it on and off.

Here's the program .

You first created an Issue, but ignored every part of the issue template? To be able to help you should answer the questions in the template.

Your "random" part is covered by the FAQ.

AC units are usually using states, that means you don't get "one IR code for one button" this is also somewhat covered by the FAQ, but you should first deal with your random data, which is most likely due to incorrect wiring or bad receiver. (Again covered by the FAQ)
