Wireless Irrigation System Using Mobile Phone
Abstraction–The purpose of this work is simplify the irrigation system
utilizing cellular telephone. It is a radio control system for exchanging on/off
of H2O pump by which a husbandman can easy command the irrigation
of his field from any location. In rural country, changelesselectricity
fluctuation and irregular power handiness are day-to-day jobs
faced by many husbandmans for a long clip. To rectify such type of
job, we developed a radio irrigation system. Farmer merely
demands to name a fixed figure and so he can supervise the irrigation
system easy. So this system will alleviate the adversities of husbandmans
by replacing the manual control of H2O pump with the radio

There have been drastic socio-economic developments in the
life of both rural and urban people since the debut of
nomadic phones in India. With latest promotions in engineering
and mass production of nomadic phones in the market, they have
been used in every walk of life which includes mechanization
work. The agribusiness industry is no manner behind in including
these technological promotions [ 1 ] .
With the approval of modern engineering, the crude method
of agricultural plants is now altering and advanced methods
are being introduced in it. Again the human head ever demands
information of involvement to command systems of his/her pick. In
the age of electronic systems it is of import to be able to command
and get information from everyplace [ 2 ] . So this system
allows us to upgrade the irrigation system with the aid of
Using this system, the husbandman can command the irrigation from any
topographic point. So he can provide the proper sum of H2O in his field.
As a consequence, the production of his harvests will be much better.
II. PROPOSED SYSTEM
Previously, husbandmans were dependent to the rain H2O. Now with
the progress in agricultural system, they supply H2O with the
H2O pump in their field. But as electricity crisis is a common
matter, frequent power failures is major hinderance for irrigation.
Again their field is far from their abode sometimes. So it
becomes hard to supervising the irrigation system ever.
So we have developed a radio irrigation system which is
controlled by an electronic device based on DTMF ( Duel Tone
Multi Frequency ) engineering. By this, the husbandman can command
the H2O pump through nomadic phone. When he sends any
signal in the device, it responses with the bid. It switches
on/off the H2O pump harmonizing to the input by the husbandman.
DTMF ( Duel Tone Multi Frequency ) :DTMF is a generic
communicating term for touch tone ( a Registered Trademark of
AT & A ; T ) . The tones produced when dialing on the computer keyboard on the
phone could be used to stand for the figures, and a separate tone
is used for each figure. However, there is ever a opportunity that a
random sound will be on the same frequence which will trip up
the system. It was suggested that if two tones were used to
represent a figure, the likeliness of a false signal occurring is
ruled out. This is the footing of utilizing double tone in DTMF
communicating. DTMF dialing uses a computer keyboard with 12 buttons.
Each key pressed on the phone generates two tone of specific
frequences, so a voice or a random signal can non copy the
tones. One tone is generated from a high frequence group of
tones and the other from low frequence group [ 2 ] . The
frequences generated on pressing different phone keys are
shown in the Table 1.

Table 1: Frequency generated on cardinal imperativeness.
Fig. 1: Hardware of the proposed device
The developed device for the irrigation system consists of some
constituents such as DTMF IC, micro-controller, relay etc. In
this undertaking, we have used DTMF decipherer IC ( MT8870 ) to
bring forth the frequence. The relay operates the motor of H2O
pump harmonizing to the bid given on the Mobile.
III. WORKING PROTOTYPE
The system works through DTMF engineering. Here, we have
to utilize two nomadic phone, one should be kept with the device
and another will be operated by the husbandman. Farmer merely have to
call to another Mobile and imperativeness the predefined key to run
the H2O pump.
Fig. 2: Use in existent life
When the husbandman makes a call to another phone, the operation
starts with it. Then he presses the denoted button on his phone.
It creates tones which is transferred to the other phone and
received by the DTMF decipherer circuit. Then it filters the signal
and gives the end product. There are four end products which are denoted
by Q1, Q2, Q3 and Q4. Each button generates different tone and
the end product are besides created harmonizing to the tone. The end product is
given below in table 2.

* 941 1336 1 0 1 1
# 941 1477 1 1 0 0
Table 2: End product for different keys
So we have to choose which button we want to utilize to run.
Then that matching end product is sent to the micro-controller.
After that, micro-controller will direct the pulsation to relay. Now
relay will drive the motor. In this manner, the husbandman can easy
run his operation system. The block diagram of this
working process is given in figure 3.

IV. RESULTS & A ; DISCUSSIONS
As this device aids to command the motor of H2O pump
wirelessly, so it will assist to salvage the ingestion of power.
Again we don’t have to be present to exchange on/off the H2O
pump. So no more manual control will be. As we can provide
the H2O in the field seasonably with the aid of this device, so the
production will be much bigger and the husbandman will be
benefited. The device is based on relay which can run really
high H2O pumps. Again the cost of this device is really low. So
that is rather low-cost for the husbandman. The husbandman can command
the H2O supply to his field from any topographic point of the universe by merely
pressing a button on his Mobile phone which is great for
nonreader husbandmans. So with the execution of this undertaking, we
can easy decrease many troubles in our agricultural system.
This proposed system provides an option to decrease the work of
irrigation with the aid of nomadic engineering. It helps non merely
to command the irrigation system but besides saves their clip needed
to go to their field in order to exchange on/off the H2O pump.
So there needs none to supervise the irrigation system instead
timely irrigation can be easy ensured. So the production cost
will lees than old which will be good for the husbandman.
At-last we will promote the husbandmans to utilize this engineering for
bettering their irrigation system to do maximal net income as
good as to cut down the hard-work in monitoring H2O pump.
