2. INTERODUCTION:
Turbidity a key idea in the context of liquids since it is an important part of
liquid dynamics and is also used to determine the calibre of water. The degree
to which a liquid is cloudy or opaque is referred to as turbidity. This happens
because as air is compressed, it is filled with countless small invisible
particles that resemble white smoke. A liquid's turbidity is directly inversely
correlated with the amount of free suspended particles, which means that as
the number of particles rises, so will the turbidity. Light waves scatter when
they travel through liquids because of these microscopic particles. So let's
talk about what turbidity is and how to use an Arduino to test the turbidity of
a liquid in this lesson. It is possible to connect an Arduino to a pH metre and
to further evaluate the water's purity, check its pH-level. The evaluation of
amount of the transparency loss brought on by water's suspended particles.
The TSS (Total Suspended Solids) could be estimated using a measurement
of turbidity. The Arduino turbidity sensor measures the amount of turbidity to
assess the water's quality. The rate of light scattering and transmission, that
can be used to evaluate whether there are suspended particles in water, are
influenced by the concentration of TSS.

3. ABSTRACT
Turbidity has an indication that the liquid has been contaminated. In the testing
process, turbidity in water can only be measured by sampling. To be able to maintain
the quality of water, required a tool that can monitor and measure the level of turbidity
of water in real time. water turbidity sensor SEN0189 is a sensor that works by
measuring the amount of light from infrared led into the phototransistor that will
produce the output voltage on the sensor. The study was conducted to be able to
characterize the ability of sensors in detecting water turbidity. The method used is to
test the sensors using sediment soil that has been filtered with a diameter of Water is a

5. SELECTED THEME : ENVIRONMENTAL
CONSERAVATION
• It is used to decte the water level by using different senors
• It is used in many factorys,chemical plants,and electrical
substation,and other liquid storage
• They are used in river and stream gaging, waste water and effluent
measurements control instrumentation for settling ponds, sediment
transport and laboratory measurements.

6. •The lab testing and analysis takes some time and hence the lab results
does not reflect real time water quality measurement due to delay in
measurement.
•Solution:
•By using the turbidity sensor we observe the water quality in fraction
of seconds

 hear we take UNO arduino USB cable to make code for the water sample
 we take resistor with 220 ohms to protect the equiment
 we take the bread board and jumper wires to connect the ardunio and water
sample
