Abstract
This paper mainly focuses on the controlling of home appliances remotely and providing security
when the user is away from the place. The system is SMS based and uses wireless technology to
revolutionize the standards of living. This system provides ideal solution to the problems faced by
home owners in daily life. The system is wireless therefore more adaptable and cost-effective.
The HACS system provides security against intrusion as well as automates various home appliances
using SMS. The system uses GSM technology thus providing ubiquitous access to the system
for security and automated appliance control.
Keywords: Short Message Service (SMS), Global System for Mobile communication (GSM),
Radio Frequency (RF), AT Commands, ubiquitous access and Automation.
Introduction
The aim of the paper is to investigate a cost effective solution that will provide controlling of
home appliances remotely and will also enable home security against intrusion in the absence of
home owner.
The motivation is to facilitate the users to automate their homes having ubiquitous access. The
system provides availability due to development of a low cost system. The home appliances control
system with an affordable cost was thought to be built that should be mobile providing remote
access to the appliances and allowing home security.
Home security has been a major issue where crime is increasing and everybody wants to take
proper measures to prevent intrusion. In addition there was a need to automate home so that user
can take advantage of the technological advancement in such a way that a person getting off the
office does not get melted with the hot climate. Therefore this paper proposes a system that allows
user to be control home appliances ubiquitously and also provide security on detection of
intrusion via SMS using GSM technology.
Related Work
Delgado, Picking, and Grout (2006) consider the problems with the implementation of home
automation systems. Furthermore the possible solutions are devised through various network
technologies. Several issues affecting home automation systems such as lack of robustness, compatibility
issue and acceptability among the old and disabled people are discussed.
Ciubotaru-Petrescu, Chiciudean, Cioarga, and Stanescu (2006) present a design and implementation
of SMS based control for monitoring systems. The paper has three modules involving sensing
unit for monitoring the complex applications. A processing unit that is microcontroller and a
communication module that uses GPRS modem or cell phone via serial port RS-232. The SMS is
used for status reporting such as power failure.
In their paper, Conte and Scaradozzi (2003) view home automation systems as multiple agent
systems (MAS). In the paper home automation system has been proposed that includes home appliances
and devices that are controlled and maintained for home management. The major task is
to improve performance.
In their paper, Alkar and Buhur (2005) propose an Internet Based Wireless Home Automation
System for Multifunctional Devices. This paper proposes a low cost and flexible web-based solution
but this system has some limitations such as the range and power failure.
Murthy (2008) explores primary health-care management for the rural population. A solution
proposes the use of the mobile web-technologies providing the PHC services to the rural population.
The system involves the use of SMS and cell phone technology for information management,
transactional exchange and personal communication.
Characteristics of HACS
The proposed system characteristics involve remote controlling of appliances, intrusion detection,
system security and auto-configuration such that system automatically adjusts the system settings
on running hardware support check. The system has useful features such as displaying of battery
level, charging status and signal strength of the mobile thus making system reliable.
Strengths of HACS
HACS system has many advantages such as remote controlling of home appliances, availability
and ease of users. The user can get alerts anywhere through the GSM technology thus making the
system location independent. The system contains low cost components easily available which
cuts down the overall system cost.
Moreover system alerts user about breach via SMS providing home security also it allows secure
access due to pre-configured number. The ease of deployment is due to wireless mode of communication.
GSM technology provides the benefit that the system is accessible in remote areas as
well. The system reliability increases due to the useful features such as battery level checking,
charging status and signal strength indicating the system about threats.
