Hello,

Can somebody explain on how to control an appliance (to do simple project) by sending SMS from a mobile phone device ?

What are the requirements for the end device (hardware and how also to program it) ?

Kindly suggest.

Tks in advance,
Balaji K

You need a cellphone module and a paid SMS card to insert into it:

Just the Cell phone module:

You the need to hook up a uC to the thing and figure out how to communicate with it. After that whatever you can code is whatever you can do.

On a second, read you mean sending the message from a cellphone TO the appliance when it is wired to a land-line? You are looking for a simple phone modem I take it?

a gsm modem or a mobile phone with data interface(usb/rs232) , knowledge about the AT command set (since the phone will look like a modem from the data transfer port), An application running on a microcontroller(ASM) or PC(VB/VC/...) communicating with the phone. And the inerface with this control unit to the devices u want to control
