TITLE 2 : Advanced Control Web Based Home Automation with Raspberry Pi Publication : International Journal of Advance Research, Ideas and Innovations in Technology. Author : Prof. Dr. Ashok .J, Chavan J. J, Patil P. V, Naik P. S Description : This Home automation system provides the user with the webpage of various lights and appliances within their home with using the raspberry pi model by the webpage. Abstract : The aim of this project is to develop a system that will provide a control of home appliances by using web page when the home host not at home. This paper is mainly concerned with the automatic control of light or any other home appliances using the internet. It is meant to save the electric power and human energy. This project is made with the help of the raspberry pi. For this paper, of course, you will need a Raspberry Pi board. In this paper, we used a Raspberry Pi model B with the Wi-Fi dongle. The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. The raspberry pi board contains a processor and graphics chip, program memory (RAM) and various interfaces and connectors for external devices. The raspberry pi can be used for many of the things that your desktop PC does. However, one key aspect that makes the raspberry pi so brilliant for schools is its ability to execute “Python” coded programs.

Aim of Project : • The technology offers new and exciting opportunities to increase the connectivity of devices within the Home for the purpose of Home automation. • Mobile devices are ideal in providing a user interface, they are portable and their wide range of capabilities. They can communicate with the Home automation network through an internet gateway, and also it can also directly, as these devices usually implement low power communication protocols, such as Wi-Fi. • It is proposed to control various Home appliances like Tube light, Door Lock, Switch and Fan using android mobile. This whole system will be controlled by ESP 8266 Wi-Fi module. Our mobile is connected to ESP 8266 Wi-Fi module through internet. One will able to select appliances from the mobile, as command will be given to the ESP 8266. According to that command this Wi- Fi module will give signal to relay switching circuit to turn ON/OFF particular Electrical appliance.

Hardware Components Used : 1.ESP 8266 Wi-Fi Module : The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU ( Micro Controller Unit ). This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections . Specifications of ESP 8266 Wi-Fi module : • 802.11 b/g/n protocol • Wi-Fi direct ( P2P ), soft-AP • Integrated TCP / IP protocol stact • It requires 3.3 V power • 13 GPIO-PINS

2. Router : A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. 3. Solid State Relay : A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Specification of relay : • 230 V input supply • 15 A current capacity • 50 Hz frequency

Software Used : 1. Android :  Android is an open source and Linux based operating system for mobile devices such as smartphones. It offers a unified approach to application development for mobile devices which means developers need only for android and their application should be able to run on different devices powered by android.  It is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touch screen mobile devices such as smartphones and tablets.  Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input.

Software Used : 2. Arduino IDE :  The open-source Arduino Software (IDE) makes it easy to write code and upload it to the board. It runs on Windows, Mac OS X, and Linux. The environment is written in Java and based on Processing and other open-source software.  A program for Arduino may be written in any programming language for a compiler that produces binary machine code for the target processor. Atmel provides a development environment for their microcontrollers, AVR Studio and the newer Atmel Studio  A program written with the IDE for Arduino is called a sketch. Sketches are saved on the development computer as text files with the file extension .ino. Arduino Software (IDE) pre-1.0 saved sketches with the extension .pde.

Work done in 7th Semester : We studied and compared ESP 8266 with Arduino and Raspberry Pi Firstly in beginning of our project we observed many sample projects based on Internet of Things ( IoT ). After finalizing the project we compared different types of modules like ESP 8266 , Raspberry pi and Arduino . After observing and comparing these three we were satisfied with ESP 8266 in many aspects and started working on it.

Configuring ESP8266 Wi-Fi module with mobile To activate the inbuilt wi-fi of ESP 8266 we have performed these steps : • We firstly wrote lua code through which we were able to assign gateway, SSID (name of wi-fi –“esp_test”), IP address and password (12345678) to ESP8266. • Then we loaded programmed to ESP8266 with the help of ESplorer. • After loading programmed in wi-fi module we connected it with mobile wi-fi as shown in fig below. • Here ESP8266 finally works as “hotspot” which can be observed in mobile phone

Configurations of wi-fi Shown below are the configuration of wi-fi module after loading the programme : • IP address of wi-fi is 192.168.1.2 • Its gateway is 192.168.1.1, Its link speed is 54Mbps and frequency is 2.4GHz

Interfacing of Wi-Fi module with web page • We have written programmed for Web Page and loaded it into ESP8266 with the help of ESPlorer. • To access the web page, one should be connected with ESP8266 through wi-fi. • Web page can be accessed only when we enter the IP address in the address bar of the web browser. • The created web page can be used to switch ON / OFF the appliances without any type of physical connection.

Controlling of relay with ESP8266 wi-fi module : Here we have connected two pins of relay one with ground and another pin is connected to GPIO pin of ESP 8266. We have connected the phase of 230v supply directly to the bulb and one end of neutral is connected to the common of the relay and the other end is connected to normally open (NO) pin of the relay.

Work done in 8th semester : • We interfaced the NodeMCU ESP8266 with the Router using Static IP. • We Developed an Android Application for all compatible Android Device. • We operated the Electronic Appliances with Android Application via Internet.
