1 like68 views
This document describes a smart home system that uses Google Assistant for voice control. Sensors like DHT11 measure temperature and humidity and send the data to Adafruit IO cloud server. IFTTT is used as a broker between Google Assistant and Adafruit IO. Voice commands are given to Google Assistant, which triggers IFTTT applets to control devices connected to a Wemos microcontroller. The sensor data is displayed on Adafruit IO dashboards and devices like lights and fans can be switched on/off remotely using voice commands through Google Assistant. The system was implemented and tested successfully.

1. INTRODUCTION
Home Automation is a building automation for a home,
called a smart home or smart house. Home automation
system controls lighting, climate, entertainment systems,
and appliances on the users command. It might be voice
controlled or switch control. It also includes home security
such as alarm systems and access control. When connected
with the Internet, home devices become key constituents
of Internet of Things. In home automation, a device which
is to be controlled is connected to central hub or
“gateway”. The user interface for control of the system
uses tablet, wall-mounted terminals or desktop computers,
Web interface, or a mobile phone application,, that may
also be accessible off-site through the Internet.
1.1 PROPOSED SYSTEM
The proposed Home automation system is a more forward
Home automation system using server, cloud, and sensors.
Server is used for tracking and controlling different
devices and saving the values in the cloud. In this system
IO.ADAFRUIT is used as cloud for storing different sensors
values. Google Assistant is used for giving feed to IFTTT.
IFTTT serves as broker between them.

The main objective of this Paper is to design and
implement a control and monitor system for smart house.
Smart house system consists of many systems that
controlled by LabVIEW software as the main controlling
system in this paper. Also, the smart house system was
supported by remote control system as a sub controlling
system. The system also is connected to the internet to
monitor and control the house equipment's from anywhere
in the world using Lab VIEW [3].
2. SYSTEM REQUIREMENT
2.1 ARDUINO IDE
The ARDUINO integrated development environment
(IDE) is a cross platform application
(for Windows, macOS, Linux) that is written in the
programming language Java. It is used to write and upload
programs to Arduino compatible boards, but also, with the
help of 3rd party cores, other vendor development boards.
The Arduino IDE also supports the languages C and
C++ using special rules of code structuring. The Arduino
IDE supplies a software library from the wiring project,
which provides many common input and output
procedures. User-written code only requires two basic
functions, for starting the sketch and the main program
loop, that are compiled and linked with a program
stub main() into an executable cyclic executive program
with the GNU toolchain, also included with the IDE
distribution. The Arduino IDE appoints the
program avrdude to convert the executable code into a text](https://image.slidesharecdn.com/irjet-v6i3951-190921091757/85/IRJET-Smart-Home-using-Google-Assistant-IFTTT-1-320.jpg)

file in hexadecimal encoding that is loaded into the Arduino
board by a loader program in the board's firmware.
2.2 IFTTT
IFTTT stands for If This Then That. It is a free web-based
service for creating chains of simple conditional
statements, called as applets. These applets are triggered
by changes that occur within other web services such
as Gmail, Facebook, Telegram, Instagram, Google Assistant
or Pinterest.
For instance, an applet is capable of sending an e-mail
message if the user tweets using a hashtag, or copy a photo
on Facebook to a user's archive if someone tags a user in a
photo. In addition to the web-based application, the service
runs on IOS and Android.
2.3 ADAFRUIT.IO
Adafruit.io is a cloud service that is managed by the
company. We have to connect to it over the Internet. It is
primarily used for storing and retrieving data. But it
performs a lot more than that. It presents our data in
real-time, online, and make our project internet-
connected to read sensor data, Control motors and also
Connect projects to web services like Twitter, Gmail,
Google Assistant, RSS feeds, weather services, etc. It also
Connect our project to other internet-enabled
appliances. Adafruit.io is meant to handle and visualize
multiple feeds of data. Various functions like displaying
data from a temperature-humidity sensor alongside data
from an air quality sensor and add a button to turn on or
off the air-conditioner or bulb or fan in your room.
2.4 GOOGLE ASSISTANT
Google Assistant is an artificial intelligence powered
virtual assistant developed by Google which is
basically available on mobile and smart home devices.
Google Assistant can engage in two-way conversations
living behind company's foregoing virtual assistant.
Moreover it is available in different languages
providing comfort to customer.
2.5 MQTT
MQTT is an extremely simple and lightweight
messaging protocol. It stands for Message Queuing
Telemetry Transport. Its publish/subscribe
architecture is designed to be open and easy to
implement, with up to thousands of remote clients
capable of being supported by a single server. MQTT
reduces device resource requirements and network
bandwidth while attempting to ensure reliability and
delivery [4].
3. HARDWARE REQUIREMENT
3.1 WEMOS D1 R1
The WeMos D1 R1 is the microcontroller with an inbuilt
ESP8266EX Wi-Fi board which uses similar layout as the
Arduino. It operates at a voltage of 3.3V. It is a
development board which is compatible with the Arduino
IDE. Many existing Arduino shields can be plugged directly
into the board as it includes standard Arduino headers. It
has 11 digital input/output pins with one analog input pin.
It has 4Megabytes of flash memory along with a clock
speed of 80MHz-160MHz.
3.2 RELAY
A relay is a switch which is operated electrically. Most of
the relays use an electromagnet to mechanically operate a
switch, including other operating principles also, such
as solid state relays. Relays are used in applications where
only one signal is necessary to control a circuit or several
circuits must be controlled by one signal.
3.3 JUMPER WIRES
Jumper wires are simply wires that have connector pins at
each end, allowing them to be used to connect two points
to each other without soldering. Jumper wires are
generally used with prototyping tools and with
breadboards in order to make prototyping easy to change a
circuit as required.
3.4 DHT11 SENSOR
A humidity sensor senses, measures and regularly
updates the relative humidity present in the air. It
measures both air temperature and moisture. Relative
humidity is expressed as a percent. It is the ratio of actual
moisture present in the air to the highest amount of
moisture air at that temperature can hold. The warmer the
air, the more moisture it can hold, so relative humidity
changes with variations in temperature.](https://image.slidesharecdn.com/irjet-v6i3951-190921091757/85/IRJET-Smart-Home-using-Google-Assistant-IFTTT-2-320.jpg)
