ABSTRACT:
This project 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.
INTRODUCTION
A typical home automation system allows one to control house hold appliances from a centralized control unit. These appliances include lights, fans, air conditioners, television sets, security cameras, electronic doors, computer systems, audio/visual equipment, etc. These appliances usually have to be specially designed to be compatible with each other and with the control unit for most commercially available home automation system
The project “Implementation of a Low-Cost Home Automation System”,demonstrates a system that can be integrated into a building’s electrical system and allows one to wirelessly control lights, fans, and turn on or off any appliance that is plugged into a wall outlet.
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 project 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.
CHARACTERISTICS OF HACS:
The proposed system characteristics involve remote controlling of appliances, intrusion detection, systemsecurity 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.
Constraints of HACS:
The system functionality is based on GSM technology so the technological constraints must be kept in mind. The system is vulnerable to power failure but this disruption can be avoided by attaching the voltage source thus allowingusers to avail the great advantage of this system.
Results:
The results of the HACS system:-Figure 2 shows various GSM hardware tests that will be
run to check the hardware support. The system then opens the serial port for communication with the GSM modem. On successful port opening the system communicates with the GSM Modem but if fails system does not communicate. The system checks support for battery level, signal strength and GSM modem SMS sending and receivingcapability. If these tests succeed the system gives response of ‘Ok’, if not then ‘ERROR’ is returned.
DESIGN SPECIFICATION:
Home appliance control system is based on GSM network technology for transmission of SMS from sender to receiver. SMS sending and receiving is used for ubiquitous access of appliances and allowing breach control at home. The system proposes two sub-systems. Appliance control subsystem enables the user to control home appliances remotely whereas the security alert subsystem provides the remote security monitoring. The system is capable enough to instruct user via SMS from a specific cell number to change the condition of the home appliance according to the user’s needs and requirements. The second aspect is that of security alert which is achieved in a way that on the detection of intrusion the system allows automatic generation of SMS thus alert.
CONCLUSION AND FUTUREWORK:
In the paper low cost, secure, ubiquitously accessible, auto-configurable, remotely controlled solution for automation of homes has been introduced. The approachdiscussed in the paper is novel and has achieved the target to control home appliances remotely using the SMS-based system satisfying user needs and requirements. GSMtechnology capable solution has proved to be controlled remotely, provide home security and is cost-effective as compared to the previously existing systems. Hence we canconclude that the required goals and objectives of HACS have been achieved. The basic level of home appliance control and remote monitoring has been implemented. The
system is extensible and more levels can be further developed using automatic motion/glass breaking detectors so the solution can be integrated with these and otherdetection systems. In case of remote monitoring other appliances can also be monitored such that if the level of temperature rises above certain level then it should generate
SMS or sensors can also be applied that can detect gas, smoke or fire in case of emergency the system will automatically generate SMS. In future the system will besmall box combining the PC and GSM modem. This hardware can be imported from Taiwan and Singapore. The hardware will be self-contained and cannot be prone toelectric failure. This appliance will have its own encapsulated UPS and charging system.
