Abstract

Home is the place where people spend the most time with family and friends and also a place to rest after a day of work. Moreover, in this pandemic era, most people work from home so it is very important to create a comfortable and safe place to live. However, for those with disabilities and the elderly, the problem of wasting electricity bills is one of the big problems in their lives. This is because they are not able to turn off the fan, lights, and television at all times. Especially in the living room of the house. Thus, voice-activated home automation using NodeMCU has been developed to provide an overview of how disabled and aged people can control their home appliances such as fans, lamps, and television through voice commands using the mobile application in their smartphone. This paper also shows the development of how the automated home using google assistant voice recognition can be connected with NodeMCU. The home automation system used a NodeMCU as a microcontroller to control the input and output of the system while google assistant acted as a transmitter to transmit the data to the mobile applications respectively. IFTTT is used to interpret the voice command from the user before sending the voice data into the transmitter and being delivered to the control unit of this project which is NodeMCU. Then, NodeMCU will control the turning on or off the process of the entire appliances in the living room. The result of this project is the electricity wastage problems have been reduced and a voiceactivated system is a more effective way to use among disabled and aged people since they do not have to type but just use voice as the input. This project is user-friendly as it introduces a better improvement to the internet of things technology by using voice commands to control certain devices at home.
