2. The main problem we are going to solve is
avoiding the uncomfortable environment for
aquatic life growth.

3. *Our aquatic wildlife are important sources of
food, energy, jobs, atmospheric oxygen,
buffers against new diseases, pests, and
predators, and protection against food
shortages and global climate change.

4. 
We found some solutions to provide a
comfortable and suitable environment for the
better survival of aquatic life. That is by using
IoT by considering some parameters like pH,
temperature, etc...

1.Arduino UNO
2.Jumper wires
3.pH sensor
4.Temperature sensor
5.Servo motor
6.Relay
7.Bread board
8.Water level sensor.

6. Arduino UNO is an open-
source codable board,
Which is generally used for
communicating with the
devices like sensors and
machines. Here we used
this to execute our
program and control the
dives used based on their
threshold values.

The DS18B20 is a
small temperature
sensor with a built-in 12bit
ADC. It can be easily
connected to an Arduino
digital input.
The DS18B20 reads with
an accuracy of ±0.5°C from
-10°C to +85°C and
±2°C accuracy from -55°C
to +125°C. We used this to
measure the temperature of
water which affects the pH
of water.

8. 
Servo motors are great
devices that can turn to a
specified position. Usually,
they have a servo arm that
can turn 180 degrees.
Using the Arduino, we can
tell a servo to go to a
specified position and it
will go there. As simple as
that!

9. 
A water level
sensor is used
to measure
the level of
water or any
liquids, this
can be easily
used with
Arduino it
works at a
voltage of
3.3v, this will
give us the
analog outputs
when
connected.

10. *
Jumper wires

11. It is a device used to
control the high
voltage devices even
by making use of the
low voltage like 5v
whenever we require
a specific device of
high voltage to be
operated by a
microcontroller we
use this relay as an
interface.

13. 
The pH Sensor looks like a rod usually made of a glass
material having a tip called “Glass membrane” . This
membrane is filled with a buffer solution of known pH. We
used this in our project for regular supervision of the pH
level of the water, which plays a vital role in the growth of
aquatic life.

Where Q= Reaction coefficient
E = mV output from the electrode
E0 = Zero offset for the electrode
R = Ideal gas constant= 8.314 J/mol-K
T = Temperature in ºK
F = Faraday constant = 95,484.56 C/mol N = Ionic Charge

17. 
Our project works on the basis of Internet of Things using Arduino. All the
components are connected to arduino in which code is built with required
threshold values to the respective components. pH sensor is used to check
the pH of the water, whenever it is low, base quantity is added and when
high, acid quantity is added with the help of servomotor, which is also
used to provide food to the aquatic species by fixing time intervals as per
our requirement. Temperature sensor is used to check the temperature of
the water, whenever high or low it adds water with the help of pump
connected to relay. Water level sensor is used to monitor the level of
water, whenever water level is low, pump is turned ON, when it is high,
pump is turned OFF. Oxygenator is used to provide oxygen to aquatic
species.

18. By providing a proper environment aquatic life
population will be increased.
Economy earned from aquatic life can be
more.
Prevent the extinction of many species.
Feeding of aquatic animals can be
automated.
