INTRODUCTION
The importance of maintaining good water quality is to increasing
the need for advance technology to help monitor the water
condition and maintain the water condition. However ,In this paper
,we are using the lake water for monitoring that provides some
important service such as water for drinking, domestic purpose
,sites for recreational activity ,and important fisheries and also
agricultural purpose .If pollution are involved in lake water ,then it
can reduce the quality of water and so that it is unsafe to drink as
well as harm organism that lives in water. The negative collisions of
climate change and inconsistency are compounding the accessible
challenges. As a result, increasing number of human activities has
progressively speed-up contagion and damage to fresh water
resources in the lakes. This traditional advance of water quality
monitoring based on variety and subsequent analyses in water
laboratories is exclusive, time- consuming and has a low promise
both in time and space. In this paper, a planned IOT based water
quality monitoring system sample is presented. The system consists
of a ARM7 microcontroller, a set of water quality sensors, and a
network connection module. It measures water quality parameters
including Turbidity, electrical conductivity (EC) values in
immediate. The experimental results showed that the system has
great prospect and can be used to operate in real world
environment for optimum control of aquaculture environment.
Furthermore, the prototype is suitable for long-term outdoor
environments and implement low-cost gateway module. The Smart
Water Quality Monitoring System will measure the following
water parameters for analysis; Conductivity and level monitoring.
While monitoring these parameters, it is perceived that one should
receive a stable set of results. Therefore a continuous series of
anomalous measurements would indicate the potential
introduction of a water pollutant and the user will be notified of
this activity with the aid of IOT technology. False positives, such
as anomalous readings over a short period of time, will be
recorded but not treated as an alert. Hence, with the successful
implementation of this monitoring approach.
LITRATURE SURVEY
A. IOT Based Water Quality Monitoring
This paper investigates a real-time water quality monitoring
system by using a proposed broker less publisher subscriber
(pub/sub) architecture framework. On the system, sensors sense the
water measurement metrics, including temperature, pH, and
dissolved oxygen level. All collected data are stored in a database
and computed stochastically for further analysis on water quality.
A complementary experiment compares the proposed pub/sub
architecture and MQTT, a lightweight protocol on which IoT mostly
uses, to show better performance of the proposed architecture in
case of network latency and throughput for diverse message
payload size, thus suggesting the future IoT implementation of the
system.

B. Water Quality Monitoring Using Interner of Things
The paper suggests an Internet of Things (IoT) based system
implementation by embedding the Radio Frequency Identification
(RFID) system, Wireless Sensor Network (WSN) platform and
Internet Protocol (IP) based communication into a single platform
for water quality monitoring (WQM) purpose. The suggested radio
frequency for the proposed WSN communication to be deployed in
vegetation area is 920MHz. The measured water parameter in this
proposed system is pH level by using an analog pH sensor.

C. Water Quality Monitoring and Control
The main reason for need of effective and efficient monitoring and
control of water quality in lakes, rivers and sea tends to keeping the
human resources healthy and sustainable, and to increase
population growth and urbanization. Due to climate changes and
variability so many huge impacts are caused by the water system to
the natural environment. Incredible methods are used by collecting
water samples, testing and analyses in water laboratories alone. In

this paper, Water Sensor Network (WSN) system prototype is
developed for water quality monitoring in Lakes is presented. These
kind of growth was introduced by the assessment of widespread
atmosphere that including accessibility of cellular network
coverage at the site of process.

2. Block Diagram Explanation
In today’s world the water monitoring is of major concern. In
majority of cases the water which is supplied is contaminated. For
this a robust method for water quality monitoring is required.
Keeping this in mind we have designed a Embedded hardware
which will monitor the quality of water and display the results on
android APP. In our project we have considered the scenario of
Society based water tank which is situated below the ground. The
water is then pumped into the overhead water head tank for use of
people. Here the µC will continuously monitor the water quality by
measuring the water turbidity to check for impurities suspended in
water and conductivity sensor to check content of water. If both the
parameters are within set limits then the water is certified to for
drinking. Here we are also designing a system for water
management. The watchman will have a local APP which is
connected to embedded hardware via WIFI. The user can request to
turn on Motor. The µc will check whether water in the base tank is
more than set point. If the water is less then motor is stopped.
Also the water allotted to the society tank is limited. We have
interfaced a water flow sensor. The µC will continuously sense the
water quantity released. If the water released is more than set
point then water is stopped. In this way we are managing the water
distributed to societies using water flow meter. Here if the water is
purity is high the µC will send all the sensor data to APP over WIFI.
The APP will compare the sensor readings with internal set points
and display the output to be fit for drinking.
The Local APP will send all the data to IOT based APP once in a
day to log the water quality and water quantity released every
day. Local app is used to develop to send the data to the end user.
MQTT is a machine-to-machine (M2M)"Internet of Things"
connectivity protocol. In the proposed system water quality
parameters are measured by different sensors. So in order to meet
all these requirements and technologies is used such as MQTT
which allows publishing and subscribing of data between the
sensors and end device. And with the help of MQTT algorithm there
will be simultaneous flow of data between sensors and the server.

4. Protocol Used (MQTT protocol)
MQTT is a machine-to-machine (M2M)/"Internet of Things"
connectivity protocol. It is an extremely lightweight
publish/subscribe messaging transport. It is useful for
connections with remote locations where a small code footprint is
required and/or network bandwidth is at a premium. MQTT is
a publish/subscribe protocol that allows edge-of-network devices
to publish to a broker. Clients connect to this broker, which
then mediates communication between the two devices. Each
device can subscribe, or register, to particular topics. In the
proposed system water quality parameters are measured by
different sensors. So in order to meet all these requirements and
technologies is used such as MQTT which allows publishing and
subscribing of data between the sensors and end device. And with
the help of MQTT algorithm there will be simultaneous flow of data
between sensors and the server. The main purpose of using IOT
approach to monitor water quality using MQTT algorithm is to
develop a system which provides end user a useful data used.
Conventionally, the water sample are collected from different
places and tested rigorously by scientist in the laboratory using
many techniques to determine the water quality. Therefore older
method where time consuming process but now IOT has the
potential to modernize the water production, as more and more of
its technology is connected to the web. This IOT approach is far
better than conventional methods since it is cost friendly, faster and
easy to use. Security is an essential factor for any system security at
both the device and network level is critical to the operation of IOT.
5. Android APP
The Water Quality mobile app is a water-monitoring data-
collection and learning tool designed for use by educators and their
students, citizen scientists, and researchers. The app helps users log
and share data they collect in the field, interpret the data through
learning pop-ups, and export it to create databases. Available
for an Android (phones and tablets) mobile devices, this app
includes data entry, identification, and learning features about
chemical (e.g. turbidity), physical (e.g. water temperature,
turbidity) water-quality parameters. Mobile phone applications are
discussed, together with advantages and disadvantages of different
technologies.

continuous water quality measurements at substantially reduced
cost. The system has capability to continuously measure water
quality parameters and transmit them to a database in real-time.
The resulting values can finally send to the mobile APP by 1 minute.
With the use of mobile phones platforms, the values of measured
parameters are displayed in easy-to-comprehend as text message
format anytime and anywhere. The result can also be monitored on
IOT using the internet. In this system we observed the pH and
turbidity of the different solutions. From above results we can say
that the turbidity of water is whenever high the water purely safe
for drinking and also we can differentiate the water for different

house holding functions. The Turbidity and pH for different
solutions is shown in above graph
FUTURE SCOPE
We can add more sensors to cover the water quality more
extensively. Also we can add the feature to control the water supply
to each flat depending upon user water usage.
