Low power, intelligent, wireless, home security system for the elderly people

In this paper, we suggest a Low Power Intelligent, Wireless, Home Security System (IWHSS) for Elders. The elders can avail the services of this IWHSS, conveniently within their room. If the elder is uncomfortable with a stranger trying to get into the home, services of IWHSS can be availed. The strangers can be identified and in emergency situations where the elder feels the necessity of the external help, the police and relatives can be informed via IWHSS. In addition to informing the police, the system also activates an emergency alarm to alert the neighbors. The elders can also see the stranger at the door and make a conversation with them. The system uses GPRS Modem which is interfaced directly with PIC 16F877A microcontroller to make the system power efficient. We have used low cost RF modules, PIC 16F877A microcontroller, IR-TSOP modules and Image Capture module as part of the hardware implementation of the system. The simulation software´s used were MPLAB IDE and PROTEUS.
