A proto-type for Home Automation using GSM technology

In the present paper we have designed and implemented a typical and simple Home Automation System using GSM (Global System for Mobile Communication) technology that controls electrical devices at home from a remote location by a simple mobile phone. This is achieved by sending an SMS to receiver present at home which is in turn connected to a hardware kit. The SMS received by the receiver is transmitted to the microcontroller which reads the message and controls the appropriate device. This operation is performed by program written in assembly language code that is stored in the flash memory which is in-built into the microcontroller. The practical implementation of the present prototype has been successful to control some electrical devices using an embedded circuit via SMS.
