AbstractIn this thesis we do on GSM based irrigation water pump
controller system in order to minimize the work load of the farmer
or user. The thesis includes the back ground of GSM, irrigation
system, microcontroller and the methodology and the simulation of
the project. The working principle of the project is when the user
or farmer send text or call on the GSM in the farming place, then
the sensor in the farming detects the moisture of the farm and it
will start watering the farm. Watering is start if the moisture is
below fifty percent. The main advantage of the thesis is it reduce
the work load of the user and user can use anywhere in the world
where there is network.
IntroductionIrrigation is a specific process of artificial
supplying water to the land or soil that is being cultivated.
Traditionally in dry regions having no or little rainfall water had
to be supplied to the field either through canals or hand pumps,
tube wells. But this method had severe problems such as increase
workload of farm labor and often it lead to problem such as
over-irrigation or under-irrigation and leaching of soil. Further
there were issues like weeding, lesser yield of crop as an effect
of problem mentioned above. To solve those problems we proposed a
technology titled GSM based irrigation water pump controller. The
technology minimizes the problem mentioned before by using GSM and
microcontroller to pump water by motor. The system contain
component like power regulator, mobile phone, relay and etc. The
basic idea of this project is give birth to DTMF controlled soil
moisture sensor in which the automation process is done through the
microcontroller based technology. In the project we use one the
microcontroller which is dedicated at the water pump and it make
the heart of device. The design of system is very sensitive and
should be handled with utmost care because the microcontroller is a
5 volts device. So every small parameter should be given high
importance while designing the interfacing circuit between the
controller and water pump. The operation of system is initialized
by calling to the mobile phone which is present at the soil moister
sensor in the field. GSM based control system implements the
emerging application of the GSM technology. Using GSM networks, a
control system has been proposed so that it will act as an embedded
system which can monitor and control appliances and other devices
locally using built-in input and output peripherals. The system
allows the user to effectively monitor and control the house or
office appliance and equipment via the mobile phone set by sending
commands in the form of SMS messages and receiving the appliances
status. The main concept behind the project is receiving the sent
SMS and processing it further as required to perform several
operations. The type of the operation to be performed depends on
the nature of the SMS sent.
Objective of the project
A general objective of the project is that to irrigate water for
farming purpose using GSM to control water pump motor. To
co-ordinate GSM and motor through Short Message Service (SMS). To
effectively control the farm field moisture via SMS To eliminate
the need of physically being present in any location for tasks
during farm. Minimize power and time wastage Specific objective of
the project We do this project to reduce the workload of the farmer
by using the technology. To save time of the farmer using this
technology during watering. The project can save water by
remembering to return itself off at the right time.
Statement of the problem
Traditionally in dry regions having no or little rainfall water
had to be supplied to the field either through canals or hand
pumps, tube wells. But this mechanism is difficult for farmer and
it lead to less product and workload of farmer. To solve this
problem we use wireless technology called GSM to control water pump
for irrigation. We propose this project to reduce workload and
increase the productivity of the farmer by using GSM based
irrigation water pump controller. This project is useful for any
person whether they are educated or illiterate.
Application of GSM in irrigation
The Global System for Mobile Communication is a standard set
developed by the European Telecommunications Standards Institute
(ETSI) to describe technologies (2G and 3G) A GSM based irrigation
water pump controller system has two major technologies behind it,
primary being the GSM and secondary one is the controller or
processor. GSM (Global System for Mobile Communication) is a
standard set used to describe protocols for digital cellular
networks. This GSM facility serves as an important part for
controlling the irrigation on field and sending the results to the
farmer using coded signals to a mobile device which indirectly
controls the entire farm irrigation system. GSM is used to inform
the user about exact field condition through a SMS on user request.
The GSM model is controlled by a standard set of AT (Attention)
commands. The connections between the two mobiles are done using
GSM. The GSM module and microcontroller are connected using UART
(universal asynchronous receiver / transmitter). When the moisture
sensor senses the low moisture content of the soil, it gives a
signal to the microcontroller. The microcontroller then gives a
signal to the called mobile (which is kept in the auto answering
mode).
Advantage of the project
The major advantage of this project is it reduce the workload of
farmer. Moreover the advantage of project can be: Controls high
voltage water pumps. Feedback generated with the help of LED
indicator. Highly sensitive. Power saving. Low cost. Remote control
from anywhere in the world.
Disadvantage of the project
Although the project has many advantages, it has the following
disadvantages: Communication delays. Not work in remote areas.
Undetectable internal problems in motor.
Application of the project
GSM based irrigation water pump controller have the following
application area: Utilized for irrigation purpose. Very useful for
illiterates to operate. Can be operated from any place in the
world. No need of manual check for moisture level in soil.
Main component of the project
The major building blocks of the projects are: Regulated Power
Supply. Microcontroller. DTMF decoder. Relay with driver
(Interfacing circuit). Crystal oscillator. Reset LED indicators.

As we see from the block diagram we make use of one
microcontroller, which is dedicated at the water pump. The
microcontroller forms the heart of the devices. A relay switch to
which irrigation motor is connected which is operated through
microcontroller. Toe operate the system initially we should make a
call to the mobile phone which is present at the soil moisture
sensor in the field. That the mobile phone will be automatically
will be answered after one or two rings then the control of the
sensor in our hands by using keypad buttons of our mobile phone the
motor will be ON/OFF through relay switch.
Software we will use
PIC-C compiler for Embedded C programming.
PIC kit 2 programmer for dumping code into Micro controller.
Express SCH for Circuit design.
Proteus for hardware simulation.
