Abstract
The paper “Real time atomization of agricultural
environment for social modernization of Indian agricultural
system” using ARM7 and GSM’ is focused on automizing the
the irrigation system for social walfare of Indian agricultural
system and also to provide adequate irrigation in particular
area. The set up consists of ARM7TDMI core, which is a 32-
bit microprocessor, GSM serves as an important part as it is
responsible for controlling the irrigation on field and sends
them to the receiver through coded signals. GSM operates
through SMSes and is the link between ARM processor and
centralized unit. ARM7TDMI is an advanced version of
microprocessors and forms the heart of the system. Our
project aims to implement the basic application of automizing
the irrigation field by programming the components and
building the necessary hardware. This project is used to find
the exact field condition. GSM is used to inform the user about
the exact field condition. The information is given on user
request in form of SMS. ng. GSM modem can be controlled
by standard set of AT (Attention) commands. These
commands can be used to control majority of the functions of
GSM modem.
INTRODUCTION
32-bit ARM processor is the contemporary general
purpose microprocessor in the embedded market used in
industrial level applications.
GSM, as we know, is the most widely used mobile
technology. Using a simple Subscriber Identity Module
(SIM), it has taken the world of mobile communication to
new heights. It is based on a simple architecture. Even with
the introduction of new technologies like CDMA, GSM has
stood its strength due to its efficiency and simplicity.
Atomized irrigation is an interesting application.
Primarily for Real time atomization of agricultural
environment for social modernization of Indian agricultural
system.
WORKING PRINCIPAL
• To continuously monitor soil moisture:
In case of monitoring the soil moisture, we know that
each crop requires different moisture level.we are using a
soil moisture sensor which is based of the principle of
parallel capacitor. As we know that the voltage across the is
inversely proportional to the dielectric medium. This
principle is used to determine the soil moisture by measuring
the dielectric constant of soil. This is then informed the
centralized unit. The centralized unit will send the message
to the device of that particular subscriber. The device waits
for a certain amount of default time for which it is
programmed. When the user does not respond to the
centralized unit in default period the device continues
monitoring the field parameters and keep on sending
automatically to the centralized unit. Using the database
stored in EEPROM of ARM, the corresponding moisture
can be known by comparing the stored values and received.
GLOBAL SYSTEM FOR MOBILE COMMUNICATION
(GSM)
A GSM modem is a wireless modem that works with a
GSM wireless network. Computers use AT commands to
control modems. Both GSM modems and dial-up modems
support a common set of standard AT commands. So we can
use a GSM modem just like a dial-up modem. The main
difference between them is that a dial-up modem sends and
receives data through a fixed telephone line while a wireless
modem sends and receives data through radio waves.
GSM is one of the most vital components in our set up
since all the communication between the users and
centralized unit takes place through this modem. GSM
communicates with ARM through I2C bus.
A GSM modem can be an external device or a PC Card.
Typically, an external GSM modem is connected to a
computer through a serial cable or a USB cable. Like a GSM
mobile phone, a GSM modem requires a SIM card from a
wireless carrier in order to operate. The description of GSM
is given below.
CONCLUSION
The project is thus carried out using ARM7TDMI core
with the help of GSM technologies.
This project finds application in domestic agricultural
field. In civilian domain, this can be used to ensure faithful
irrigation of farm field, since we have the option of finding
out moisture level of soil in a particular area
