For the sake of sustainable development and amelioration of our current life style, home automation is one of our top concerns. Home automation will be useful not only for the elderly person but also for visually impaired, physically handicapped and remote patients. Though home automation can be done by using Bluetooth or RF technology; reliability, cost effectiveness must be taken into consideration before the implementation of these technologies. The goal of our project is to setup a reliable, secured, cost effective and user friendly home automation system for patient, elderly and physically handicapped people. Here arduino as processing unit and zigbee 2mW wire antenna (zigbee mesh) are chosen for this project. This project is implemented by using three node providing the provision of further node integration. Though this system is developed for residential environment, because of zigbee’s high noise immunity this system can be implemented for industrial environment by modifying its configuration.
