A new design approach of home automation system for patients with physical disability to reduce water wastage and power consumption using renewable energy

The paper demonstrates to design a smart home system for physically disabled persons with the purpose of reduction of water and power consumption. The physically disabled persons require special assistances from caretakers or other persons to lead their normal life and even at home, it is not convenient for them to control the house apparatus system according to their wish. In this paper, a smart home automation system is implemented which consists of automatic control of lights to turn on in presence of human and turn off rest of the time as well as Bluetooth remote controlling ability along with automatic door lock and open system, automatic Water tap, automatic water tank fill-up and Solar charging system with the solar controller to reduce the power consumption. The project has been implemented using low-cost components and based on Arduino platform with an aim to develop a system which will be effective to reduce water wastage in real time as well as the project will be able to reduce power consumption and utility bill by using renewable energy as the power source.
