IRForum

Dear All,

I trying to control my office AC using Arduino. The problem is I cannot turn ON my AC automatically.
I am using YORK AC. I already follow this forum https://forum.arduino.cc/index.php?topic=207517.15. But it still not working

Here's my IRRecvDump output:

Hi

This signal is not recognised in our system, which is not neccessarily an issue.

However, if you post signals for the following:

- temperature from 16->30degC (only change the temperature each time and record which value it is)
- plus both the ON & OFF signals (also identify each signal)


....I will examine them and should be able to provide a working signal. (It may take a day or 2)

If possible use the sketch on our blog: https://www.analysir.com/blog/2014/03/1 ... s-arduino/

I forgot to mention, post a photo of your receiver & transmitter circuit, plus a circuit diagram if possible

Here are the picture of my circuit. I connected the receiver on 2 and the power supply is on 5v

The IR sensor that im using is this one

I am using sketch that you give me

That may be your main issue! (if there is a "1838" in the model name)...see...
https://www.analysir.com/blog/2014/12/0 ... -revealed/

I will wait until you post all of the temperature signals (as requested above) before looking at it further. It looks like it will be straight forward to clean up.

...you didnt post any details about your IR transmitter circuit or wiring.
