Password Protected Smart Control System of Home Appliance Using SMS

Abstract

This paper presents the development of GSM-based home appliance control for smart home system. The main aim of the prototype development is to reduce electricity wastage. GSM module is used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch ON and OFF the home appliances such as light, air-conditioner, fan, water pump, door, TV etc. The system is integrated with Arduino and GSM network interface using a programming language named Processing or Wiring which is the combination of C/C++ language. Arduino software (version 1.6.8) was utilized to accomplish the integration. The system is activated when only the password authorized user sends the SMS to controller at home. Upon receiving the SMS command, the microcontroller unit then automatically controls the electrical home appliances by switching ON or OFF the device according to the user direction. In other words, it reads message from the mobile phone and responds to control the devices according to the received message. The prototype has been successfully developed and it could provide an effective mechanism in utilizing the energy source efficiently.
