AbstractOur Smart Home Automation provides a low cost effective and flexible home control and monitoring system using QR code. As Home Automation has become more and more commercial and marketable in recent years. The goal of our project is to provide comfort to old and dissabled people as scanning of QR code is a one time process and can be accussed by anyone easily.Our proposed system required ESP32 and ESP8266 microcontroller to provide wireless connections to electrical appliances.We introduce smartphone application as smartphones are commonly used now-adays and our application provides easy access to our home by using wifi module, bluetooth, scanning of QR code. The wastage of electricity can be known by notification on smartphone application. Application can be log in by using QR code or SSID.

Keywords QR Code,SSID,2-way switching,Smartphone application.

INTRODUCTION
Smart devices remains the easiest and flexible way to a smart home. Smart things are now-a-days most commonly used by smartphones (or) smart handsets. They are many benefits of using smart technology for home automation as it insures

convenience, sustainability, security, efficiency, save time etc. A smart home is a home in which all the electrical appliances are connected to a control application. So they can either be switched on and switch off at any certain time (or) any certain place. As Home automation is more secure and safes alot of time even though many people does not use it because they can't afford it the main objective of our project is to provide smart home automation which can be affordable by every individual and by introducing QR codes it because more flexible and can be managed by anyone. By using 2-way switching techniques even old people can use transitional switching method.Given below is 2-way switching technique.
HOME AUTOMATION DEVICES

(REQUIREMENTS)
- They require low maintenance.
- The relay has fast response time.
- They decrease the burden on the instrument transformer.
- Disadvantages of Electronic Relay
- The high tension supply is required for their operation.
- The power consumption in the electronic relay is very high.
- The relay has the short lifespan.
- The electronic relay is practically not used in the power system
PROPOSED SYSTEM

App is a way to interface between user &devices.App scans QR code & save connection of setting into phone. App connects the device via local station. User is physically present near the devices, if user is not near the devices it moves to cloud to connect to devices & the devices will always be connected to cloud via local routes.

Block Diagram Of Smart Home Automation

Main board consist of Esp micro controller, relay drivers, 5v supply, and relay board's. Esp checks for any update being send via cloud (or) local station & act accordingly. If user sends a signal to switch any appliances, the Esp saves the data & set (or) reset the relay accordingly & then update this data to user & cloud. The app saves the acknowledged data sent from devices. Relay driver is logic shifter since Esp cannot drive relay directly & has a logic high of 3.3v & relay needs logic high of 12v.

We use a buffer logic shifter when ever Esp sets a relay, it creates a magnetic field in the coil inside it. The input string connect's to output terminal (similar to a switch we use whenever we apply physical press on a traditional switch it connect'stherwo terminals) & current flows through the input to output & appliances turn's on. Currently we are using a local host as our cloud.
WORKING PRINCIPLE
Our home automation system has the following use-cases
1. QR code
2. SSID
3. Login
4. Add devices
5. Remove devices
The actors involved in the system are
1. User
2. Hardware
By using include relationship we can login the application and control it globally (or) by wifi (or) bluetooth.
The home automation system makes use of following classes
1. User :- User involves attributes such as Name, SSID and operations like turn on app and turn off app.
2. Room:- Involves attributes such as QR code and SSID and operation turn on light and turn off light.
3. Network :- Involves attributes like Bluetooth, Wifi, and Globally.
4. Electronic devices :- Involves attributes I'd and operations on and off. Association relationship is given between users and Room and also Network user and dependency is given between Room and
5. electronic devices.
It represent sequence and interaction of a given use case. This can show the most of information about the system. It shows the events which includes signals inputs, decisions, interrupts and actions to (or) from users (or) external devices. A sequence diagram showing smart home automation system which involves the following objects.
1. User
2. Appliances
3. Network
4. Database

8.CONCLUSION

This paper presents the new circuit topology for monitoring and controling home electrical devices by using the flexible home-based Android smart phone at a reasonable price and implemented by using ESP as well as using android app for system control configuration. The proposed new circuit topology is used in a quiet based web services in an interoperable application layer for communication between the remote user and the home device. All Android-based smart phone, the Wi-Fi connection is the support built; the home access device to control can use the phone, Wi-Fi, 3G or 4G to access the Web page on hosting server using Android App.
