Home Automation is a growing industry worldwide, where many solutions are improving quality of life through convenience as well as reduction in bills. Most of the currently available home automation systems like Google Home and Alexa Home are expensive as they require supportive appliances. And their users have to buy these costly appliances while using such home automation systems.
The proposed system is integrated with a smart-phone based android application (BLYNK Application). Home automation and security system can be controlled through voice and manual commands using android application. For voice control, the services of Google Assistant is used which is linked with the system using IFTTT (If This Then That) platform. The system controls home appliances (including Geyser, Fan, lights, etc.) through an android application running on any android supported device by using voice commands and buttons on android app, making it suitable for handicap users. The system has a master controller (NodeMCU) which connects the system to WiFi, takes instructions from end users to control electrical appliances and gas geyser. The system also consist of security features such as live streaming, smart door unlocking and wireless intercom.
For better performance, the whole system is tested repeatedly to control and monitor the appliances by voice, buttons on application and by using manual traditional switches in case of unavailability of internet. The results obtained by using voice controlled feature as well as button control feature are acceptable with great accuracy level. The Automation system is useful for controlling and monitoring of home appliances. It is also a helpful solution for handicapped persons as they can easily control home appliances by only using their voice.
