The term Home Automation refers to the automatic control of household features activity and appliances. It means this features of activity are controlled by using internet to make life more convenient. It is a set of hardware electronic and communication that work to integrate devices with one another by the use of internet. This paper describes a smart home automation system with the help of QR codes. QR Code has been used to switch â€œonâ€ and â€œoffâ€ the light bulb by using mobile scanner application. A Mobile Scanner application has been designed for this project to scan QR codes, and this application has been designed for android mobile. The NodeMCU has been used to control the light bulb. After scanning QR code the Android application sent the command to web based application. NodeMCU is already connected with the internet and fetching command in real time with web based application. The two types of commands are used with the help of programming I.e. on and off. So what type of command has been received by NodeMCU, depending upon what type of QR code has been scanned by the user. This system and project is very unique and can be easily process anywhere in the world while scanning the QR Code with develops secure application.
