Abstract: The initiative is designed to build up an
automatic drip irrigation system for controlling the pump
motorize ON/OFF by sensing the moisture content of the
soil. In the field of crop growing, scarcity of water is of great
apprehension thus make use of appropriate technique of
irrigation is essential and drip irrigation prove to be most
effective in this. The lead intended is for trimming down
human involvement and ensure proper irrigation with
abridged water consumption.
The project uses ATMEGA 16 microcontroller which is
programmed to receive the input signal of changeable
moisture condition of the soil through the BJT based soil
moisture sensor. For comparator we are using Op-amp to
create an interfacing channel between microcontroller and
sensing array.
An output for driving relay to operate water pump is
generated when controller receives signal. Liquid crystal
display interfaced with microcontroller for displaying the
status of soil in different pots and water pump’s on/off
status. Sensor arrangement is created with two wires or stiff
metallic rod inserted a distance apart.
Also this includes 3 flower pots which are different saplings
and hence require different water content. This is why it is a
more efficient technique of water supply as compared to
conventional technique of flood irrigation method. To
enhance this initiative GSM module is implemented that
delivers a message whenever water pump switches on/off
along with soil moisture status for example dry or moist for
all 3 different pots.

1. INTRODUCTION
This graduate project defines the implementation of a
mobile driven intelligent and completely automated
wireless drip irrigation system. The system together
provides a very advanced control over the currently
implemented manual system. The implementation
involves use of valve control, drip control and pump
control using a microcontroller based board.
A mobile phone is used to interface the microcontroller
board via a GSM modem and control the valve timings. An
additional LCD board is provided to collect moisture and
temperature level feedback from various types of plants
with different moisture content. This helps the user in
collecting different feedback for different types of the
moisture level with separate breeds of crops that can be
cultivated accordingly. The concept is enhanced by
integrating GSM technology, such that whenever the water
pump switches ON/OFF, an SMS is delivered to the
concerned person regarding the status of the pump.
All the above features are distinct and hence making it
better than projects already existing also few more such
advantages are differential feedback from each plant,
pump and valve control to manage flow to individual
drips, complete monitoring over text message, for
different seasons variable valve timings can be saved. This
it is easy to control as well as beneficial from small ranging
home arrangements of flower to varied farm crops.

3. BLOCK DIAGRAM EXPLAINATION:
a) Power supply block:
The 230v 50 Hz AC mains supply is step down to 12v using
step down transformer. The transformer gives output of
12v which is AC, thus it is rectified with the help of Diode
Bridge W10M. The output of W10M is DC 12v and is
further filtered by a 1000 microfarad capacitor, and then it
is regulated using IC 7805. The output produced is +5v dc
that is given to microcontroller for its operation.

b) LCD (Liquid crystal display):
Liquid crystal display is connected to circuit for displaying
the message like motor ON/OFF, soil moisture condition
c) THE SENSOR DESIGN AND FUNCTIONING:
The sensor is constructed using a transistor 2N2222
a 10Kiloohm variable resistance pot,100 ohm
resistor and two probes as shown in Fig.2 these
probes consist of two thin wires which can be
immersed into the soil or water under test. The
circuit gives a voltage output corresponding to the
conductivity of the soil. The soil or air between the
probes acts as a variable resistance whose value
depends upon the moisture content in the soil.

d) Microcontroller:
This graduate project uses a ATMEGA 16 microcontroller
due to its varied distinct features and it is a suitable
microcontroller for embedded control applications also it
is a low power high performance CMOS 8-bit with 8kb of
flash memory. On chip flash allows the program memory
to be reprogrammed in-system or by a conventional non-
volatile memory programmer. It includes 32
programmable I/O lines as well as it is compatible with
MCS-51 family products.
e) Relay:
The relay used here works as electrically operated
switch. Current to be flowing through the coil of the relay
will create a magnetic field that will attract lever and will
change the switch contacts. The coil current can be on or
off so relays have two switch positions and most have
double throw (changeover) switch contacts.
4. EXPERIMENTAL SETUP:
The experimental setup includes a power block which
converts the output voltage to 12V using a step down
transformer which supplies power. It also includes a
microcontroller to which is connected a LCD screen, all the
sensors giving input to the microcontroller which
processes it in real time and displays it on screen also
sends a binary signal to the GSM modem connected to it
which sends a message on the registered mobile number.
The GSM modem uses the same supply voltage as the
microcontroller.
It includes 3 solenoids which are used for the purpose of
valve operation and these are connected to the drip pipe
also called as industrial drip pipe supplying water to the
plants.
The setup also includes an AC motor which has a speed of
1000 rpm. There are 3 soil moisture sensors for the 3
different plants. It includes relay as well as a resistor and a
transistor as seen in the setup.
