ABSTRACT
Indian agriculture is diverse ranging from impoverished farm villages to developed
farms utilizing modern agricultural technologies. Facility agriculture area in China
is expanding and is leading the world. However, its ecosystem control technology
is still immature, with low level of intelligence. Promoting application of modern
information technology in agriculture will solve a series of problems facing by
farmers. Lack of exact information and communication leads to the loss in
production. This system provides an intelligent monitoring platform framework
and system structure for facility agriculture ecosystem based on IOT. The Internet
of Things makes everything connected.
Over 50 years since independence, India has made immense progress towards food
productivity. Modern agriculture practices have a great promise for the economic
development of a nation. So we have brought-in an innovative project for the
welfare of farmers and also for the farms. There are no day or night restrictions.
This is helpful at any time.

INTRODUCTION
1.1 WHAT IS SMART IRRIGATION
Agriculture is the major source of income for the largest population in India and is
major contributor to Indian economy. However, technological involvement and its
usability have to be grown still and cultivated for agro sector in India. Although
few initiatives have also been taken by the Indian Government for providing online
and mobile messaging services to farmers related to agricultural queries and agro
vendor’s information to farmers. Based on the survey it is observed that agriculture
contributes 27% to GDP, and Provides employment to 70% of Indian population.
IoT is changing the agriculture domain and empowering farmers to fight with the
huge difficulties they face. The agriculture must overcome expanding water
deficiencies, restricted availability of lands, while meeting the expanding
consumption needs of a world population. New innovative IoT applications are
addressing these issues and increasing the quality, quantity, sustainability and cost
effectiveness of agricultural production.
Agriculture is the backbone of Indian Economy. In today’s world, as we see rapid
growth in global population, agriculture becomes more important to meet the needs
of the human race. However, agriculture requires irrigation and with every year we
have more water consumption than rainfall, it becomes critical for growers to find
ways to conserve water while still achieving the highest yield. But in the present
era, the farmers have been using irrigation technique through the manual control in
which they irrigate the land at the regular interval.

According to statistics, agriculture uses 85% of available freshwater resources
worldwide, and this percentage will continue to be dominant in water consumption
because of population growth and increased food demand. There is an urgent need
to create strategies based on science and technology for sustainable use of water,
including technical, agronomic, managerial and institutional improvements. By
using Internet technology and sensor network technology we can control water
wastage and to maximize the scientific technologies in irrigation methods.

interconnecting communicating objects that are installed at different locations that
are possibly distant from each other. Internet of Things (IoT) is a type of network
technology, which senses the information from different sensors and makes
anything to join the Internet to exchange information.
It can also be used to modify the status of the device. The central processing unit
will also include communication device to receive data from the sensors and to be
relayed to the user’s device. This will be done using a higher communication
device such as a Wi-Fi module. The data processed by the central module is
converted to meaningful data and relayed to the user.
The user can view the data with the help of a handheld device such as a mobile
phone or a tablet. Nowadays water scarcity is a big concern for farming. This
project helps the farmers to irrigate the farmland in an efficient manner with
automated irrigation system based on soil moisture.
The proposed system has been designed to overcome the unnecessary water flow
into the agricultural lands. Temperature, moisture and humidity readings are
continuously monitored by using temperature, moisture and humidity sensor and
send these values to the assigned IP address. Android application continuously
collects the data from that assigned IP address. Once the soil moisture values are
exceeded the particular limit then the relay, which is connected to the arduino
microcontroller controls the motor. The android application is a simple menu
driven application, with 4 options. This includes motor status, moisture,
temperature and humidity values. The motor status indicates the current status of
the pump.

3.2 DHT11 TEMPERATURE AND HUMIDITY SENSOR
DHT11 digital temperature and humidity sensor is a composite Sensor contains a
calibrated digital signal output of the temperature and humidity. Application of a
dedicated digital modules collection technology and the temperature and humidity
sensing technology, to ensure that the product has high reliability and excellent
long-term stability. The sensor includes a resistive sense of wet components and an
NTC temperature measurement devices, and connected with a high-performance 8-
bit microcontroller.
They consist of a humidity sensing component, a NTC temperature sensor (or
thermistor) and an IC on the back side of the sensor. For measuring humidity they
use the humidity sensing component which has two electrodes with moisture
holding substrate between them. So as the humidity changes, the conductivity of
the substrate changes or the resistance between these electrodes changes. This
change in resistance is measured and processed by the IC which makes it ready to
be read by a microcontroller.
On the other hand, for measuring temperature these sensors use a NTC temperature
sensor or a thermistor. A thermistor is actually a variable resistor that changes its
resistance with change of the temperature. These sensors are made by sintering of
semi conductive materials such as ceramics or polymers in order to provide larger
changes in the resistance with just small changes in temperature. The term “NTC”
means “Negative Temperature Coefficient”, which means that the resistance
decreases with increase of the temperature.

3.4 DC PUMP
A 9 volt DC motor is any of a class of rotary electrical machines that converts
direct current electrical energy into mechanical energy. The most common types
rely on the forces produced by magnetic fields. Nearly all types of DC Pumps have

change the direction of current flow in part of the motor.
DC Pumps were the first type widely used, since they could be powered from
existing direct-current lighting power distribution systems. A DC Pump's speed
can be controlled over a wide range, using either a variable supply voltage or by
changing the strength of current in its field windings. Small DC motors are used in
tools, toys, and appliances.

3.8 RECTIFIER CIRCUIT
A rectifier is an electrical device that converts alternating current (AC), which
periodically reverses direction, to direct current (DC), which flows in only one
direction.
The process is known as rectification, since it "straightens" the direction of current.
Physically, rectifiers take a number of forms, including vacuum tube diodes, wet
chemical cells, mercury-arc valves, stacks of copper and selenium oxide
plates, semiconductor diodes, silicon-controlled rectifiers and other silicon-based
semiconductor switches.
Fig. 3.8.1 Rectifier
Historically, even synchronous electromechanical switches and motors have been
used. Early radio receivers, called crystal radios, used a "cat's whisker" of fine wire
pressing on a crystal of galena (lead sulfide) to serve as a point-contact rectifier or
"crystal detector".
Rectifiers have many uses, but are often found serving as components of
DC power supplies and high-voltage direct current power transmission systems.

Depending on the type of alternating current supply and the arrangement of the
rectifier circuit, the output voltage may require additional smoothing to produce a
uniform steady voltage. Many applications of rectifiers, such as power supplies for
radio, television and computer equipment, require a steady constant DC voltage (as
would be produced by a battery). In these applications the output of the rectifier is
smoothed by an electronic filter, which may be a capacitor, choke, or set of

3.9 BATTERY
Battery, in electricity and electrochemistry, any of a class of devices that
convert chemical energy directly into electrical energy. Although the term battery,
in strict usage, designates an assembly of two or more galvanic cells capable of
such energy conversion, it is commonly applied to a single cell of this kind.
KANPUR INSTITUTE OF TECHNOLOGY Page 37
Fig. 3.9.1 Battery
Every battery (or cell) has a cathode, or positive plate, and an anode, or negative
plate. These electrodes must be separated by and are often immersed in
an electrolyte that permits the passage of ions between the electrodes.
The electrode materials and the electrolyte are chosen and arranged so that
sufficient electromotive force (measured in volts) and electric current (measured
in amperes) can be developed between the terminals of a battery to operate lights,
machines, or other devices.
Since an electrode contains only a limited number of units of
chemical energy convertible to electrical energy, it follows that a battery of a given
size has only a certain capacity to operate devices and will eventually become
exhausted. The active parts of a battery are usually encased in a box with a cover
system (or jacket) that keeps air outside and the electrolyte solvent inside and that
provides a structure for the assembly.

6.2 RESULT
Mechanism of the system starts with switching on of the power supply followed by
resetting the microcontroller then the copper wires (which act as sensing
arrangement) which will be connected to comparator will sense the dampness of
the soil.
The output of the comparator will control the operation of the system. If the output
of the comparator is logic low then the motor will be turned on and the status of the
motor as on and that of the soil as dry will be displayed on the 1st and 2nd line of
the LCD respectively.
Else if the output of the comparator is logic high then the motor will be turned off
and the status of the motor as off and that of the soil as wet will be displayed on the
1st and 2nd line of the LCD respectively.

CHAPTER 7
ADVANTAGES AND DISADVANTAGES
7.1 ADVANTAGES
Prevents Disease and Weeds
Specialized drip irrigation systems direct water specifically to each plant's root
ball, rather than sprinkling the entire garden like a typical rainstorm. As a result,
surrounding weed seeds cannot germinate, so you'll have less weeding to do. Water
at the roots also prevents leaf diseases caused by standing droplets on the foliage.
Because the water does not strike the leaves or flowers, blight diseases have no
chance of proliferating.
Conserves Water and Time
Hand watering with a hose or watering can takes substantial time and early
morning and evening watering rituals take away from family and work. Both drip
and sprinkler irrigation systems have timers that can be preset for daily or weekly
watering so you do not need to monitor the watering because the timer shuts the
water off when it has finished. Your water bill should be lower if the irrigation
system is effective.
Preserves Soil Structure and Nutrients
Watering with a wide open garden hose may allow too much water to seep into the
soil. As a result, nutrients leach out with the water runoff, leaving the plants with
fewer nutrients available. The soil may also become compacted when you water
with a hose. Plants may show signs of withering or root disease with suffocating,
compacted soil. Using either drip or sprinkler irrigation produces smaller droplets,

Gardening Flexibility
If you have a busy schedule, you'll appreciate being able to work in the garden at
the same time as the plants are being watered. While one garden section is being
watered, you can plant and prune in another area.
7.2 DISADVANTAGES
1. Agriculture being a natural phenomenon relies mostly on nature, and man
predict or control nature let it be rain drought sunlight availability. pests control
etc. So ever implementation IoT system agriculture.
2. The smart agriculture need availability on internet continuously. Rural part of
the developing countries did not fulfill this requirements. Moreover internet is
slower.
3. Fault sensor or data processing engines can cause faulty l decisions which may
lead to over use of water, fertilizers and other wastage of resources.
4. The smart farming based equipment require farmer to understand and learn the
use of technology. This is the major challenge in adopting smart agriculture
framing at large scale across the continues.
5. It also has some issues which have to be tracked properly in order to attain the
full benefit of it.
6. The current IoT systems are not scalable or reliable and the initial costs are high
which the farmers cannot afford.

Using this system as framework, the system can be expanded to include various
other options which could include mobile application control of motor and wifi
controlled monitoring. These will expand the working capability and efficiency of
this prototype. It can be implemented not in agriculture but in gardens in any
places using the sprinkler concept. It has a vast scope when it is mixed with IOT
.Automation will get a new dimension through this.

CONCLUSION
The automatic irrigation control using NODE MCU has been experimentally
proven to work satisfactorily and we could successfully set the timer and managed
to control the motor over time. This process not only records values of temperature
and humidity it also controls the motor accordingly. Analyzing the weather
condition motor will automatically maintain water supply making it possible to
maintain greenery without human intervention.
