This is the state of art microcontroller which is the first of its kind to have an Inbuilt wi-fi transceiver and microcontroller which also receives commands from any remotelocation web, access to control the electrical loads.

Automation is the method of operating a variety of engineering processes, equipment, machinery

(2)

and other applications with the mechanism of control systems. Also there will be no human intervention in this method.

The method of operating home appliances without human intervention is known as Home automation using various control system techniques. The electronic appliances such as fire alarm, fan, outdoor lights, lights, kitchen timer, etc., in the home can be automated using various control techniques.

The cloud is used to send the sensor data to the Google assistant through Wi-Fi module and then a decision tree is implemented which decides the output of the electronic devices and also it is used to achieve the power control and local data exchanging.

Aim of the Project

The project aims at designing an advanced home automation system using normal web server and Wi-Fi technology. The devices can be switched ON/OFF and sensors can be read using a Personal Computer (PC) through Wi-Fi. Home automation has different kinds like remote control home automation, mobile phone home automation. This project is based on a wireless control home automation system, which could help to save energy like electricity and lots of physical strength using the internet.

The Internet of Things technology is used to come in with innovative idea and large development space for smart homes to improve the living standards of life. The growth of the Internet of Things will reform a number of sectors, like healthcare, automation energy, transportation, etc.

Cloud computing can be used in such case to implement the IoT infrastructure that augmented with sensors and actuators to monitor and control “things” from anywhere.Cloud computing provides scalable computing power, storage space and applications, for developing, maintaining, running home services, and accessing home devices.

Home Automation

Home automation has different kind like remote control home automation, mobile phone home automation.

This project is based on wireless control home automation system, which could help to save energy like electricity and lots of physical strength using internet.

Home automation system is the procedure how people can get automated performance from all devices which we cannot get with our physical efforts.

Voice Recognition based Home Automation

The wireless communication between the smartphone and the Arduino UNOis done through Bluetooth technology. This will be morehelpful for handicapped and aged people who want to control appliances by speaking voice command. The disadvantage of this method is that communication between voice recognition tool and user is dependenton signal to noise ratio (SNR). The accuracy of the system will be less if the noise of the voice signal is high since it affects the communication highly.

Working Principle

Fig. 1.Block diagram

A Wi-Fi Module is used to access the internet configured with any nearby wireless modem.

Loads can be controlled and monitored using a web page. The user can give commands through the allotted IP and these commands are received byWi-Fi module. The program within the Wi-Fi Module executes the received commands based on which the load gets activatedthrough TRIAC and Opto-coupler interfaced to Wi-Fi Module.

TheCloud-based-Networking system helps tostore and maintaining data over the Internet location. This helps users to have access to the data from any location on the planet.

IoTusers can send commands to the hub even from a distant or remote location over the cloud network. The sensors will receive the signal from the hub to trigger and perform the user- requested action. The status of the action will be updated by hub. Once the action is performed, it willbe taken to the cloud network and in this way users can control and monitored very aspect of their smart homes.

NODEMCU ESP8266

NodeMCU is an open-source based firmware developed for the ESP8266 wifi chip. By exploring functionality with the ESP8266 chip, NodeMCU firmware comes with the ESP8266 Development board/kit i.e. NodeMCU Development board. NodeMCU Kit/board consist of ESP8266 wifi enabled chip. The ESP8266 is a low-cost WIFI chip developed by Espress if Systems with TCP/IP protocol. There is Version2 available for NodeMCU Development Kit NodeMCU Development Board v1.0 (Version2), which usually comes in black coloured PCB.

Relay

A relay is an electrically operated switch. Electromagnet is used to operate a switching mechanism or other operating principles are also used by the relays. Relays are used to control a circuit by a low-power supply.

The operating principle of relay is a magnetic field is created by the current flowing through the coil which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions and most have double throw switch.

WI-FI Module

Wi-Fi is a networking technology used for exchanging the information between two or more devices without using cables or wires. There are different types Wi-Fi technologies are A, B, G, N and AC. Here, in this project Wi-Fi module is used to receive commands from the internet and activate loads through TRIAC &Op-tocoupler by executing a program written within the Wi-Fi module.

OPTO-Coupler

The package of light emitting device and light sensitive device without any electrical connection is called as an Op-tocoupler or Op-toisolator. Connection between the light emitting devices&

light sensitive devices, beam of light is used. The light emitting device is an LED and light sensitive device is a TRIAC. Thus, Op-tocoupler and TRIAC are used to drive loads based on the signal received from the Wi-Fi module.

Voltage Regulator

It is an electronic device used for regulating voltage in a power system. There are various types of voltage regulators are used such as variable voltage regulator & fixed voltage regulators which

(5)

are subdivided into several types like electro-mechanical, automatic voltage regulator, linear, hybrid regulators, etc. Here, we are using 3.3V voltage regulator to provide required power supply to a Wi-Fi module from 5V SMPS power supply.

Web Server

A web server is a program that serves content using the HTTP protocol. This content is frequently in the form of HTML documents, images, and other web resources, but can include any type of file. The content served by the web server can be pre-existing or generated on the file. In addition to the web-based application, the service runs on IOS and Android.

Cloud Computing

The cloud based approach provides a secured real time monitoring and controlling via internet over different systems at home from any desired location, without the need for a large memory to store devices data, or any added hardware. Cloud computing relies on sharing or storing the data which is given as input through theweb server.

Using a mobile application as a user interface and a microcontroller to connect different devices,the user can also control the devices using thecloud networking.
