Hello Everyone,

I'm quite new here.

I was wondering if you guys could help me out with GSM relay activation cuircuit.

It's a cuircuit in which you can activate and de-activate a relay using your mobile phone.

Moreover, an SMS containing a command can be sent to the cuircuit and it will reply with the data you need.

Let's say you have connected this cuircuit to a 12VDC lamp. You may turn the lamp ON and OFF using your mobile phone and you can send an sms to it, in which it will reply of the status wether the lamp is ON or OFF.

Any insights will be much appreciated.

Thanks
