7. ABOUT THE PROJECT
In today's era, technology can enhance human life.
Technology is evolving decade by decade.
Automation was a science fiction earlier but not
today. By combining latest technology with home, we
can build an awesome home. With the Arduino UNO
and Windows 10, we can build a home automation
system that is capable of operating home devices
automatically.

8. GETTING STARTED
Before starting the project, lets understand basics
first. Consider the following image (overall
configuration):

9. OVERALL CONFIGURATION

10. CONFIGURATION FOR ROOM
Now considering room scenario, an Arduino UNO will
control devices and reads sensor data. The figure
"Room Architecture" depicts how the Arduino UNO will
connects with the devices and sensors. Room have
multiple controllable devices(i.e. Light(s), Fan, Wall
Socket(s), etc.), one Passive IR (to detect human
presence in the room), one temperature sensor (LM35
to collect room temperature) and LDR (to detect light
intensity near room window).

11. ROOM SCENARIO

12. CNFIGURATION OF DIFFERENT
SENSORS
Servo Motors
Servo motors are geared DC motors with the closed-loop circuitry
incorporated within them. The basic configuration of a servo motor
composed of a DC motor, gearbox, potentiometer and control circuit.
DC motor is used to move a gearbox with a large reduction ratio. The
final shaft imposes a force on the external load and simultaneously
acts on the axis of the feedback potentiometer. So, the potentiometer
senses the position of the axis and sends a corresponding voltage to
an operational amplifier.

13. This voltage compared to the input voltage, that determines the desired
position of the shaft, producing a voltage in the output of the
comparator. This voltage powers the motor such that the shaft moves
in the necessary direction to align with the angle that corresponds to
the voltage applied to the input.
SERVO MOTOR
CONFIGURATION

14. LM35
A precision IC temperature sensor with its output
proportional to the temperature (in oC). The sensor
circuitry is sealed and therefore it is not subjected to
oxidation and other processes.

15. PIR
The pin configuration of the PIR sensor is shown in the
figure. PIR sensor consists of three pins, ground, signal, and
power at the side or bottom. Generally, the PIR sensor
is up to 5V, but, the large size PIR modules operate a relay
instead of direct output.

16. HC-05 (Bluetooth)
To make a link between your Arduino and bluetooth, do the
following: 1) Go to the bluetooth icon, right click and select Add a
Device 2) Search for new device, Our bluetooth module will appear
HC-05, and add it 3) The pairing code will be 1234. 4)after make a
pairing, we can now program the arduino and upload a sketch to
send or receive data from Computer.
