Home Automation System (HAS) has been one of the most important topics in the past
decades. The total number of smart homes in the North America and EU28+2 countries are
expected to reach 65 million by 2019. By integrating technologies into homes, HAS provides
solutions for controlling, monitoring and automating functions for homes using smartphone
applications or websites. It can be further categorized into six groups: energy management
and climate control systems; security and access control systems; lighting, window and
appliance control systems; home appliances; audio-visual and entertainment systems; and
healthcare and assisted living systems.
Some researchers have implemented micro-controller based HAS user interface on
smartphone applications. It is convenient as users are only required to download the
application once. It is also easy to operate and does not consume much memory space.
However, a drawback of this design is that users will need to familiarize themselves with
application. Some users may face difficulties in operating the application especially for those
complex and complicated systems.
Some other researchers have also implemented their HAS user interface on responsive
websites. A drawback of such design is that users may be required to remember the URL or
the server IP address to access the smart home systems. It could even more inefficient if
users are required to login with their credentials. Aqeel-ur-Rehman and his colleagues
suggested these smart home interface which based on applications and websites could be
inconvenience especially for the elderly and disabled people, and they only target a specific
group of people – those who are more familiar with the technologies and who can operate it.
The main contribution of this project is proposal, development and implementation of a
voice-controlled smart home system using Raspberry Pi and Amazon Voice Service. This
proposed implementation is inexpensive and inclusive for everyone as users are only
required to provide voice commands. This system comprises seven main features: 1)
Control of electrical appliances; 2) Entertainment system; 3) Digital memo; 4) Face
recognition control; 5) Surveillance; 6) Room occupancy detection; 7) Voice-controlled
