IR home appliances control using TI MCU

Hi,

you can find MSP430 application note in this link:

then you can find for example the following app note which might be useful for you:

Thank you Mr. Hendrawan,

Can you please tell me that how much it will cost to me to design such system. 

Thanks in advance!

To design one, it can cost you from nothing to thousands dollars. The cost of building them depends on your design and how many you are going to build. If you are talking about building a few, you will be much better off buying them money wise.

How to design a system to control home appliances with IR remote and Receiver. What MCU should I use.

With the given project outline, any MCU can be used. You should be way more specific about the application constraints.

I want to make the device which will assumed to replace the conventional switches to control the home appliances. So it will be in 24x7 working condition and should have good and quick response to command.

If you search Google for the term ‘X10’, you’ll find a wide variety of cheap devices for doing so. X10 communicates by 50Khz sound peaks on the power line. For use with a remote control, there is a RF gateway and some RF multi-purpose remotes (can be used for IR controlling the TV too). Basic functionality is on/off or dim (depending on receiver). There’s also a computer interface available that can be used to control all receivers by a PC program, or take macros (including calendar triggers) from PC for stand-alone operation.
It’s not the most modern equipment, but likely the cheapest and widest-used.
No need for doing such stuff yourself. Unless you want to enter the market with dirt-cheap high-volume products.
