Abstract - This paper presents an IoT device which helps
to manage/monitor and plan the usage of water by
observing the level of water in the tank. By using The
Internet of Things(IoT), we can regulate the usage of water
in residential/offices. The device uses sensors to record the
level of water in the tank at any instant and sendsthe datato
the cloud using Wi-Fi. The information gatheredcan be read
by users on the integrated website using their
smartphone/laptop device connected to the internet. The
device also controls the automatic functioning of water
motor by turning it on when the water level lies betweenthe
low level and the high level (the specified range) and by
turning it off when the water level falls below the low level
or rises above the high level.

1. INTRODUCTION
Internet of Things (IoT) is currently a technology of great
significance worldwide. IoT is a platform whichprovidesthe
physical devices present in the network embedded with
electronics, software, sensors, actuators, and connectivityto
connect and exchange information to addressspecificneeds.
IoT is when the internet and networksexpand themselvesto
domains such as manufacturing, transportation, healthcare
and security. An Embedded system is a combination of
software and hardware which carriesout a specific function
within a larger system. The implementation of IoT with the
help of embedded systems can help vastly with the
management of water. Water management is the complete
management of water resources under set policies and
regulations. It is the activity of planning, developing,
distributing and managing the optimumuse of water. Water
management is important to satisfy demands for water by
allocating water on an equitable basis. The foundationofthis
project is based on Internet of Things (IoT) and Embedded
Systems.
2. OBJECTIVES
Water, once an abundant natural resource, is becoming a
more valuable commodity due to droughts and overuse.
Hence, it is important to use a Tank Water Level Monitoring
system to avoid overflow by intimating the level of water in
the tank. Water controlling system implementation makes
for a potential significance in home applications.Theexisting
automated method of level detection is described as
something which can be used to turn the motor device
on/off to start the feed pump at a low level and allow it to
run until a higher water level is reached in the water tank.
This helps enhance the water management system.
3. LITERATURE SURVEY
[1] Design of a Water EnvironmentMonitoringSystemBased
on Wireless Sensor Networks:
This paper is devoted to the explanation and illustration of
our new design of water environment monitoring system,
based on a wireless sensor network. The system generally
includes three parts: hardware and software of data
monitoring nodes, hardware and software of the data base
station, and software for the remote monitoring centre. The
system's measurement capacity ranges from 0 to 80 C on
water temperature, with an accuracy of 0.5C; and from 0 to
14 on pH value, with an accuracy of 0.05. Sensors, applicable
to different water quality, could be installed at the node to
meet the monitoring demands in different water
environments and to obtain different parameters.
[2] Smart Water Monitoring System Using Wireless Sensor
Network at Home/Office:
This paper is about developing an efficient wireless sensor
network (WSN) based on water monitoring system. There
are two different ways to monitor the water: water level
monitoring and water pipeline leakage monitoring. Finally,
this is water monitoring system of smart homes/office
research concept will be completed by using wirelesssensor
technology. By using the monitoring system, we can find a
more optimal way to preserve the water, hence saving it for
the present and the future generations.
[3] Water Quality Monitoring System Using Zigbee Based
Wireless Sensor Network:
Here, the proposed implementation of high power Zigbee
based WSN for water quality monitoring systemofferinglow
power consumption with high reliability is presented. An
important fact of this system is the easy installation of the
system, where the base station can be placed at the local
residence, close to the target area. And the monitoring task
can be done by any person with minimal training at the
beginning of the system installation.

4. PROPOSED SYSTEM
In accordance with the literature survey, we are trying to
make a smart system for controlling the wastage of waterby
using an ultrasonic sensor to sense the level of water intank.
If the water tank is full or up to the maximum level the
sensor will sense it and stop the system automatically. If the
water tank is at the minimum level set by user, the sensor
will sense it, activate the motor pump and stop at the
maximum level. We can control this whole process using
IOT.

6. FUNCTIONS OF COMPONENTS
1. Arduino UNO Board
The hardware consists of an Arduino
microcontroller development board, Ultrasonic Sensorsand
a Wi-Fi module to collect & transfer data to cloud. Data is
collected from ultrasonic sensors using Arduino Uno
microcontroller. Arduino is an open source hardware
platform which is compatible with various sensors and
communication technology. There are different types of
Arduino microcontroller that are used for different
purposes. It not only control devices but also can read data
from all types of sensor. Arduino Uno is a microcontroller
board based on the ATmega328P. It is simple, low cost, easy
to use and easily available in the market. It takes 5V voltage
as input at the speed of 16 MHz. Arduino Uno contains 14
digital input/output pinsand 6 analog input pinsto connect
various sensors that gives analog inputs.

2. ESP8266-WiFi Module
The ESP8266 Wi-Fi Module is a self-contained SOC
with integrated TCP/IP protocol stack that can give any
microcontroller accessto the Wi-Fi network.TheESP8266is
capable of either hosting an application or offloading all Wi-
Fi networking functions from another applicationprocessor.
Each ESP8266 module comes pre-programmed with an AT
command set firmware, which means, one can simply hook
this up to Arduino device and get about as much Wi-Fi-
ability as a Wi-Fi Shield offers. The ESP8266 module is an
extremely cost-effective board withahugeandevergrowing,
community. This module has a powerful enough on-board
processing and storage capability that allows it to be
integrated with the sensors and other application specific
devices through its GPIOs with minimal development up-
front and minimalloading during runtime. Its high degreeof
on-chip integration allows for minimal external circuitry,
including the front-end module, and is designed to occupy
minimal PCB area.

3. Ultrasonic Sensor
An Ultrasonic sensor is a device that can measure the
distance to the target (water level) using sound waves. It
measures the distance by sending the sound waves at a
specific frequency and then listening for it to bounce back.
This helps keep track of the current level of water between
maximum water level and minimum water level assetbythe
user.

4. Motor Pump
Motor Pump is used to move water into the tank. The Motor
Pump is connected to the Ultrasonic sensor via the
embedded system. When the Ultrasonicsensordetectswater
level between the lower range and the upper range, the
motor is switched on. And when the Ultrasonic sensor
detects water level below the lower range and above the
upper range, the motor is switched off.

7. WORKING
Arduino Uno is connected to an ultrasonicsensor(HC-SRO4),
Wi-Fi module (ESP8266) that processes and transfers
recorded data using sensors to the cloud. Wi-Fi module will
trigger the Atmega 328 microcontroller, which will get +5-
volt DC supply from the supply voltage. Stored data is
accessed by the user through the web. This enables the user
to check the level of water. User logs in to the integrated
website and set the minimum water level and maximum
water level in the tank. Tank Water Level management is
used to avoid overflow by intimating the level of waterinthe
tank. Water controlling system implementation makes a
potential significant presence in homes and offices. The
existing automated method of level detection is based on
measure of minimum and maximum level of water in the
tank which facilitatesthe automaticswitchingON/OFFofthe
motor. If minimum input water level value is reached, the
Motor is turned ON. It begins to fill water in the tank until
maximum input water level value is reached in the water
tank. Once the maximum water level value is reached, the
motor is turned OFF.

9. CONCLUSIONS
The IoT is an important technological advancement which
takes the internet and networks to everyday life domains
like controlling home appliances, management of water
intake and keeping the overall energy intake under control.
It encapsulates several technologies such as information
technology, cognitive sciences, communication technology,
and low-power electronics. IoT creates a newer information
society and knowledge economy.ThedevelopmentoftheIoT
brought into light many new challengesincluding the lackof
fundamental theory supporting, unclear architecture, and

immature standards. This concept has helped improve the
basic outline of water management techniques by keeping
the user up to date by storing the information regularly,
obtained using certain variables with the help of network
sensors. The existing automated method of level detectionis
based on measure of minimum and maximum level of water
in the tank which facilitatesthe automaticswitchingON/OFF
of the motor. If minimum input water level value is reached,
the Motor is turned ON. It begins to fill water in the tank
until maximum input water level value is reached in the
water tank. Once the maximum water level value is reached,
the motor is turned OFF. The user can keep track of the
usage of water and plan accordingly the range of water level
to be administered. Thus, this device helps achieve certain
level of optimal usage of water which in turn makes water
management more effective.
