As we have seen many types of remote controls like Infra-red controlled, RF controlled, DTMF controlled etc. The present model is also intended to control devices using GSM technology i.e. just by sending code (containing numerical numbers) to the appliance/devices status. So the present project model can be used in the substations, homes, industries etc. In substations feeders are located which carry the power close to the
