INTRODUCTION
During summer, most people are too lazy to water the potted
plants on their rooftop gardens every day. So, we build a simple
and exciting automatic plant watering system that you can
build yourself in just a few hours.
It is an Arduino based automatic plant watering system that
uses a soil moisture sensor. In the present era, food scarcity
and water scarcity occur due to the increase in population. So
to avoid this problem we have to promote the agriculture
sector. But water wastage is more in this sector in the form of
water logging while watering the agricultural fields through
irrigation. Therefore an automatic plant irrigation system has
to be designed for the proper water supply in the fields. This
paper deals with an automatic plant irrigation system which
automatically senses the moisture content of the soil and
decide whether irrigation is needed or not and how much
water is needed for soil. This system uses AtMega328
microcontroller. It is programmed to sense the moisture
content if the soil over a period of time. When the moisture
content is less than the limit which is predefined, it will start
supplying the desired amount of water till it reaches the limit.
So when the soil is dry the pump will automatically water the
fields and when the soil is wet the pump will automatically
switch off, there by eradicate the need of manpower and
conserve the time.

Aims & Objectives
• The main need of the system for the agricultural sector
arises because of the loss of yield due to improper
irrigation which is quite significant.
• An automated system will deliver optimum amount of
water depending upon the soil moisture
• The manual labour cost and saves farmers from some of
the tedious field work.
• In the commercial and domestic sector like offices
workspaces and homes where there are indoor plants .
• It would be cheaper and more effective in
maintenance.
Requirement
• Arduino UNO
• 5 Volt Relay Module
• Water pump and pipe
• Soil Moisture sensor
• Jumper wire
• Arduino UNO software

Explanation of components
Arduino UNO: Arduino UNO is a
programmable microcontroller board. It
contains Atmel's ATMega328 as is based on
that microcontroller .The Arduino board also
contains an in-built voltage regulator to
protect it from burning out and supports
serial communication to help programmers.
5V Relay: Relays are basically electrical or
electromechanical switches that operate on
the principle of magnetic field controlling
the switching within the relay. A relay has
two modes of operation, normally open
and normally closed.
Water Pump: DC water pump is a small electric
water pump motor that powered by a 24v, 12v,
5v, 6v, or 3v direct current power supply, solar
panel or battery. It uses centrifugal force to
pressurize, transfer or circulating water or
other liquids.
8. 8
Soil Moisture sensor: The soil moisture sensor is
a resistive sensor that consists of two electrodes
with a small charge and the resistance in those
electrodes is measured and then the resistance
in between the soil is used to find the moisture
levels. A soil moisture sensor normally comes
equipped with an amplifier such as LM393. It has
a VCC, GND and analog output pin.
Jumper wire: A jump wire (also known
as jumper, jumper wire, DuPont wire) is
an electrical wire, or group of them in a cable,
with a connector or pin at each end (or
sometimes without them – simply "tinned"),
which is normally used to interconnect the
components of a breadboard or other prototype
or test circuit, internally or with other equipment
or components, without soldering.

Working principle
The system works on the principle of sensing and
actuation. The soil moisture sensor is intended for the
measurement of moisture in the soil which is connected to a
microcontroller (in our case an Arduino UNO). After
sensing, the sensor sends the moisture content of the soil in
that section. If it is below 20%, the Arduino will send a signal
to the relay which would actuate the pump. The pump is
connected to the solenoid valve which would deliver the water
to that particular section when it is required.
As the sensor senses the moist that is when plant will get of
water it will be sensed bye the soil sensor and will again give
signal to relay and signal will be reached to pump through relay
module and it will automatically stop supplying the water The
main advantage of using this system is to reduce human
interference and, ensure proper and timely irrigation. There is
no need of continuous monitoring to that plant if we want to
go any trip for long journey now, we can easily go by
implementing this device at our garden .It can be implemented
at anywhere in the garden or we can use it inside our houses
also, but still it will save our time as well as efforts.
The logs and information of the watering schedule is
uploaded to a cloud server called Thing Speak. This data can
be used for research in the field of agriculture.

Applications
• The smart irrigation system is user friendly platform to
learn and enhance your skill about smart watering
system.
• It can provide high accuracy water supply and avoid water
from wastage.
• Due to automatically handling, user requires less man
power.
• With the help of the sensors, it can accurately determine
the soil moisture levels.
• It can easily detect and control the temperature,
humidity, solar radiation using sensors.
• This system automatically provides water supply to the
field. User can manually operate (turn ON or OFF) valve.
• This system helps to produce good quality of crops and
improves economic condition.
• This IoT-based smart irrigation monitoring and controlling
system are very easy to increase crop.
