yes thanks i have resolved my problem.My appliances are now being controlled but can i modify the circuit of relays that you posted by attaching some temperature sensors with that circuit?? If so how to do that and which parts of circuit to modify?? Secondaly in case of appliances pc sends signal to relays when sms is recieved from gsm modem to switch the appliances but in case of relays the process is reversed. Sensors will sense any kind of temperature rise or fire and will send signals to relays that will be forwarded to pc. I dont know how to modify the circuit for sensors. Here is the circuit diagram which i followed:

If you know or have any kind of circuit diagram for this please let me know.

 

Thanks
