Voice-activated Open-loop Control of Wireless Home Automation System for Multi-functional Devices

In this modern age of technological advancements, everything seeks smarter and simpler approach. Home is a place for people needing professional care or supervision. Home automation is necessary to assure comfort, ease and convenient purposes. It refers to the automation of appliances, security and other residential functions that can be remotely controlled using devices like mobile phone, computer etc. This work resembles the design and implementation of voice controlled home automation system. The design attempts for wireless control over multifunctional devices such as light, fan and door. The proposed design provides a way in which the user is able to control the magnitude of the properties and ensures the suitable brightness and intensity of the appliances. Moreover, the design consists of an automatically operated wheel chair which can be navigated to different rooms in a house by voice commands. An android app has been developed to receive and process the voice commands from Google assistance. This proposed system uses an Embedded system (ES) as the controller which is connected to android app via Bluetooth communication for data transferring. The system can provide a huge assistance for physically challenged people with a very low cost.
