Abstract:
The rapid technological development has brought about continuous reduction in human physical effort and increase in quality of life. This has also brought about increase in the independence, comfort and security of the disabled people through the development of Home Automation System. Various means have been used to support and save the life of disabled at home ranging from GSM based control system, Bluetooth-based application, Android Based method etc. However, there is a need for the development of a low cost, multiple alert system for the disabled. In this work, a portable IP-based remote control system – WHADDA, has been developed to secure the disabled people with self-automated security devices against fire outbreak and intruder to the house coupled with full control of home electrical appliances remotely. The system was developed based on remote environment and home environment interacting together to ensure a high degree of efficiency. The command interface (on computer system and phone mobile user) component enable the user to control the electrical appliances while home gateway components were used to receive signal from the sensor which interrupt the microcontroller to activate the actuators (e.g. light and alarm). The command component is REST based service over HTTP saddles with the role of relaying commands between interface and the gateway. C# and JavaScript were used at different levels to accomplish different task during implementation phases. The XAMPP software platform was used to create and manage the database. WHADDA provides simple, cost effective and flexible solution suitable for use by disabled people.
