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 etc. The

system is integrated with microcontroller and GSM network interface using embedded

C language. MikroC software was utilized to accomplish the integration. The system

is activated when 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
