Comparative Analysis of GSM and Internet Based Home Automation Systems
Abstract
Home Automation System (HAS) is gaining popularity because of its countless advantages. Home automation refers to the monitoring , controlling and automation of home appliances remotely. This paper deals with comparative analysis of GSM and Internet based HAS. The performance has been analyzed on the basis of cost, security, real time monitoring, status, user friendly environment, Graphic User lnterface(GUI) etc. The Home Automated System (HAS) based on Internet not only controls but also provide real time monitoring and status of home environment through sensors whereas GSM based home automation only control home appliances but not provide real time status of appliances. The GSM based HAS is more secure as compared to Internet based Home Automation System (HAS). GSM based HAS sets a Pin code on SIM (Subscriber Identity Module) which is inserted in GSM module and also accurate AT (ATtention) commands which is given in program while Internet based system requires webpage to login through personal Gmail account. Internet based Home Automation System (HAS) has user friendly GUI which shows easy ON/OFF buttons for home appliances and real time graphs of sensors data. Whereas in GSM based HAS only define SMS format for user. GSM based system is cost efficient as compared to Internet based system. Besides all these advantages including cost efficiency, GSM based HAS lacks in providing the today 's most advanced and more innovative HAS features of real time monitoring and status of home environment through PIR Motion and LM35 temperature sensors.
