Configurable ZigBee-based control system for people with multiple disabilities in smart homes

Abstract : Nowadays, home appliances manufacturers are increasingly relying on wireless sensor network and single chip embedded technologies to build smart environment. Many existing systems are already in the market, however, they were designed without envisioning the need of residents with special needs. This work presents a framework that enables the integration and control of devices within a smart home environment for residents with disabilities. The framework supports the integration of multiple control devices for different residents with different disabilities. Moreover, the work addresses the safety of the users by providing warnings and notifications in case of an emergency. A prototype was designed, implemented and tested.

 EXISTING SYSTEM :

 ? Most of the existing smart home monitoring and control systems do not accommodate special needy users to manage their home appliances. ? Many existing systems are already in the market, however, they were designed without envisioning the need of residents with special needs. ? In terms of connection variant, this project proposed mixture of wired and wireless connection, where wired connection will run from the home appliances to the main control board while wireless connection will only exist in between the main control board and the UI platform, which is the phone or PC connected via Bluetooth.

 DISADVANTAGE :

 ? The problem in their system is that WSN nodes always make radio transmission in a very short period of time. ? However, in spite of technological advances in IoT and HAS over the past decade, the inability to use such technologies is bigger issue than their cost. ? Enabling a single remote access to a single corresponding server in a smart home household will also resolve the issue on „too many control terminals?. ? One of the existing issues that are associated to smart home applications are the fact that in a home with all sorts of automated application, there will be too many remote controls or monitoring terminal, if the user installed a range of proprietary applications from different providers.

 PROPOSED SYSTEM :

 • This work proposes a framework for properties to permit persons with different types of disabilities the manages of appliances and gadgets within their dwelling atmosphere. • The proposed system saves the time to recognize the status of the devices. • The ARM7 is a general purpose 32-bit microprocessor, which offers high performance and very low power consumption. • This work proposes a framework for homes to enable people with different types of disabilities the control of appliances and devices within their home environment. • The proposed work enables the user to perform his/her daily activities by remotely monitoring and controlling home appliances without depending on others.

 ADVANTAGE :

 ? A wireless sensor device is a battery-operated device that has the capability of sensing physical quantities, provides efficient wireless communication and data storage. ? The implemented system provides home residents with disabilities to take advantage of the advancement in technology. ? It enables them to perform their daily activities by remotely monitoring and controlling their home appliances without having to depend on others. ? The proposed work enables the user to perform his/her daily activities by remotely monitoring and controlling home appliances without depending on others. ? The Door and Doorbell node are connected to an RFID tag reader and a pressure senor which allows the node to perform two operations.
