A Smart Control System of Home Appliances using SMS

Abstract

This paper is about the development and implementation of a GSM based password protected control system for electrical home appliances that enables to control remotely. GSM module is used for receiving short message service (SMS) from user#x2019;s mobile phone that automatically enable the controller to take any further action such as to switch ON or OFF the home appliances such as lights, air-conditioners, fans, water pumps, door locks, TVs etc. Hardware of the system has been developed using an Arduino Uno board, a GSM modules, some switching relays and some other easily available electronic components. The driving software has been made using the Arduino IDE. The system is activated when only the user sends the SMS to the controller at home with the exact password. Upon receiving the SMS command, the microcontroller unit will decode the received SMS automatically and controls the electrical home appliances by switching ON or OFF the device according to the user direction.
