3. Introduction
Home Automations IOT
 Home automation is
building automation for a
home, called a smart home
or smart house. A home
automation system will
control lighting, climate,
entertainment systems, and
appliances. It may also
include home security such
as access control and alarm
systems. When connected
with the Internet, home
devices are an important
constituent of the Internet
of Things ("IoT").

5. Components Required
 RELAY
 NODE MCU ESP8266
 BATTERIES
 LED BULBS

6. RELAY
 Relay technology is also
promising in Internet of
Things (IoT) applications.
In IoT, relaying can have
many more functions in a
cellular network, such as
improving the topology of
the cellular network,
improving the robustness
of a network, and
decreasing power
consumption

7. NODE MCU: ESP8266
 Node MCU is an open
source IoT platform. It
includes firmware which
runs on the ESP8266 Wi-Fi
SoC from Espressif
Systems, and hardware
which is based on the ESP-
12 module. The term
"Node MCU" by default
refers to the firmware
rather than the
development kits.

8. BATTERIES
 A battery is a source of
electric power consisting of
one or more
electrochemical cells with
external connections for
powering electrical devices
such as flashlights, mobile
phones, and electric cars.

9. LED BULBS
 Because LED lights are
naturally friendly to digital
controls (they include a
semiconductor to produce
light), they are perfectly
suited for IoT applications.
IoT LED lighting is the ideal
way to realize maximum
savings—and gain the
valuable operational
insights that can improve
all aspects of your building
management.

10. SOFTWARE REQUIREMENT
 BLYNK APP:
 Blynk is a Platform with IOS
and Android apps to
control Arduino, Raspberry
Pi and the likes over the
Internet. It's a digital
dashboard where you can
build a graphic interface for
your project by simply
dragging and dropping
widgets

11. ANDROID SOFTWARE
 The Arduino Integrated
Development Environment
is a cross-platform
application that is written
in functions from C and
C++. It is used to write and
upload programs to
Arduino compatible
boards, but also, with the
help of third-party cores,
other vendor development
boards.

 Natural language-based voice assistants.

18. CONCLUSION
 The home automation using Internet of Things has
been experimentally proven to work satisfactorily by
connecting simple appliances to it and the appliances
were successfully controlled remotely through internet.
