INTRODUCTION

1.1 INTRODUCTIONABOUT THE PROJECT WORK

As we all know now a day’s water usage is becoming one of the biggest problems

in the world. Different methods have been developed for water conservation. Water is

been needed in each and every field. Water is an essential part of our day today life.

Hence water is been considered to be basic need of human. Water is required in

tremendous quantity in agriculture field. Water wastage is one of the major problems in

agriculture. his water wastage occur when e!cess of water is been provided to the

fields. Different techniques is been used to control or to save water wastage from

agriculture.

"n the agriculture field# the current agricultural practices need to intensify the rate

of food crop production for the rate of population growth with available resources. his

project presents the automated system to make effective utili$ation of water resources for

agriculture and crop growth monitoring using %&' and &olenoid (alve. he water use

efficiency is increased in a drip irrigation system by using soil moisture sensors and

Water level sensor. he signals from the sensors are coordinated by the microcontroller

and transmitted to the irrigation control center )"**+.

Terraced irrigation: "n this method the land is been cut into steps and supported by

retaining walls. he flat area is been used for planting and the idea is that the water flows

down each steps watering each plot. his in turns allow steep land to be used for planting

crops.

Ditch irrigation: his method is considered to be a traditional method in which

ditches are dug out and seedlings are planted in rows.

!rin"#er $%te&: "n this irrigation system sprinklers are used which is been

installed in ground and the sprinkler rises up when water pressure rises which is one of

the popular irrigation system used on parks and golf courses. "n this sprinklers moving

and setting is not required hence it saves time and timer delay as per the environmental

condition can be added for automatic watering.

water saving ofupto ;46 compared with traditional irrigation practices of

the agricultural $ones were achieved.

he automated irrigation system implemented was found to be

feasible and cost effective for optimi$ing water resources for agricultural

production. his irrigation allows cultivation places with water scarcity

thereby improving sustainability. he use of solar power in this irrigation

system is pertinent and significantly important for organic crops and other

agricultural products that are geographically isolated where the investment

in electric power supply would be e!pensive. 8urthermore# the internet

*ircumstances that we find ourselves in today in the field of

microcontrollers had their beginnings in the development of technology of

integrated circuits. his development has made it possible to store hundreds

of thousands of transistors into one chip. hat was a prerequisite for

production of microprocessors# and the first computers were made by

adding e!ternal peripherals such as memory# input0output lines# timers and

other.

location and that?s all. wo new concepts are brought to us1 addressing and

memory location. 'emory consists of all memory locations# and addressing

is nothing but selecting one of them. his means that we need to select the

desired memory location on one hand# and on the other hand we need to

wait for the contents of that location.

7et add 2 more memory locations to a specific block that will have a

built in capability to multiply# divide# subtract# and move its contents from

one memory location onto another. he part we just added in is called

@central processing unit@ )*>/+. "ts memory locations are called registers.

&uppose that as a result of some interference )which often does occur

in industry+ our microcontroller stops e!ecuting the program# or worse# it

starts working incorrectly.

Bf course# when this happens with a computer# we simply reset it and

it will keep working. However# there is no reset button we can push on the

microcontroller and thus solve our problem. o overcome this obstacle# we

need to introduce one more block called watchdog. his block is in fact

another free0run counter where our program needs to write a $ero in every

time it e!ecutes correctly. "n case that program gets @stuck@# $ero will not be

written in#and counter alone will reset the microcontroller upon achieving its

ma!imum value. his will result in e!ecuting the program again# and

correctly this time around.

-.'.>In!/t;o/t!/t /nit:

hose locations we?ve just added are called @ports@. here are several

types of ports1 input# output or bidirectional ports. When working with

ports# first of all it is necessary to choose which port we need to work with#

and then to send data to# or take it from the port. When working with it the

port acts like a memory location. &omething is simply being written into or

read from it# and it could be noticed on the pins of the microcontroller.

12


13/62

-.'.eria# co&&/nication:

As we have separate lines for receiving and sending# it is possible to

receive and send data )info.+ at the same time. &o called full0duple! mode

block which enables this way of communication is called a serial

communication block. /nlike the parallel transmission# data moves here bit

by bit# or in a series of bits what defines the term serial communication

comes from. After the reception of data we need to read it from the

receiving location and store it in memory as opposed to sending where the

process is reversed. "n order for this to work# we need to set the rules of

e!change of data. hese rules are called protocol. Data goes from memory

through the bus to the sending location# and then to the receiving unit

according to the protocol.

-.'.=Ti&er /nit:

he timer block this can give us information about time# duration#

protocol etc. he basic unit of the timer is a free0run counter which is in fact

a register whose numeric value increments by one in even intervals# so that

by taking its value during periods 9 and C and on the basis of their

difference we can determine how much time has elapsed. his is a very

important part of the microcontroller whose understanding requires most of

our time.

-.'.Ana#og to Digita# Con2erter:

As the peripheral signals usually are substantially different from the

ones that microcontroller can understand )$ero and one+# they have to be

converted into a pattern which can be comprehended by a microcontroller.

>roteus is appreciated because it is relatively easy to write short#

powerful and comprehensible scriptsQ the large number of built0in functions#

together with the e!amples in the manual# keep low the learning curve.

he development environment includes a source code editor with synta!

highlighting and a conte!t0sensitive guide. >roteus does not need to be

installed1 the interpreter is a single e!ecutable )below 344 Fb+ that does not

require additional D77s to be run on recent Windows systems.

CONCUION

=.1 CONCUION:

&ince earlier days farmer is supposed to visit their agricultural land

and check the moisture content of soil manually. "t will take minimum

human efforts this technology can be used. "t allows the user can monitor

and maintain the moisture remotely irrespective of time. "t is really an

effective and economic way to reduce human effort and water wastages.

*urrent techniques in agriculture have reduced the ground0water level and

improve the crop production. his "rrigation control system using A mobile

can help farmer in many ways to know the Humidity# Automatic and

'anual modes of operation. his system not only in agricultural fields# this

system also can be used in *ricket stadiums or %olf stadiums and also in

public gardens. his system has a huge demand and scope in crop

production. "t allows a lot of development within it and leads to the standard

and useful system which can be used vary widely in agricultural field for

betterment of crop production.

Hence#we proposed an automatic irrigation system fully controlled

using %&' and &B7=B"DA7 (A7( .Here we configured an automated

approach for the water tanker to be filled when it is empty.his project is

practically implemented and it is feasible. "t brings into focus the future

direction of water management.he irrigation has been fairly developed.
