Abstract: As we live a era of smart world, This is world of smartphones and internet using these two major factors, we can control anything from any where, by using these two factors, we implement a project of smart home automation by voice commands with the help of google assistant. Which is very much useful for people who can’t walk and for older peoples, they can control smart home devices like lights, switches, fans and other electronic devices with the help of internet by relay. Also we monitors the room temperature and humidity using dht11 sensor. The commands given through Google assistant are decoded and sends the information to the microcontroller turns into control the relay connected to it and stores the data in the cloud and can also access manually by blynk application. For this project we will build an web application called IFTTT which acts as a chain and connects the google assistant and blynk application that controls the home appliances and blynk could to store all the data and can be shown the usage graphically.

Keywords: Internet of Things, Cloud Technology, Automation and Android application.
