Abstract
Smart switch is a device which operates (ON/OFF) any electrical appliance with the help of mobile phone only by sending a SMS from any place (wherever GSM network is available). User sends a SMS to the mobile number, installed inside the GSM Module. The device first checks the authorization of the mobile number from which the SMS is received if it is from the user or not. If it is from the user, the device then compares the message body of the SMS which is treated as operating code or instruction with the predefined instruction which is already written in memory of the microcontroller & switches the state of the terminal, specified in the received instruction to ON or OFF. In user interface of the device, there is a LCD Display which shows the present status of the terminals, means which point is ON or which point is OFF, of the device. Password protection logic is used to provide protection. The password is needed to save the authorized mobile number, from where the SMSs will be received. User can also operate the switch manually by pressing keys in the keypad in user interface.
