This document describes a system for automating agricultural irrigation in India using sensors and wireless communication. The system uses an ARM7 microcontroller, temperature, humidity, and soil moisture sensors to monitor field conditions. A GSM modem sends sensor readings to users via SMS upon request. The ARM7 processes sensor data and displays it on an LCD screen. The system aims to modernize Indian agriculture by providing remote monitoring of fields and automated irrigation control.

Agriculture continues to play a major role in Indian Economy. Agriculture Sector

is changing the socio-economic environments of the population due to liberalization and
globalization. Irrigation system in India has given a high priority in economic development.
Many new concepts are being developed to allow agricultural automation to flourish and deliver
its full potential. To take full advantage of these technologies, we should not just consider the
implication of developing a new single technology but should look at the wider issues for
complete development of a system.
The paper Real time atomization of agricultural environment for social
modernization of Indian agricultural system using ARM7 and GSM' is focused on atomizing the
irrigation system for social welfare of Indian agricultural system. The project is implemented by
using advanced processor ARM7TDMI 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 SMSs 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 atomizing 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. 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.
The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time
emulation and embedded trace support, together with 128/512 kilobytes of embedded high speed
flash memory. A 128-bit wide memory interface and unique accelerator architecture enable 32-
bit code execution at maximum clock rate. For critical code size applications, the alternative 16-
bit Thumb Mode reduces code by more than 30% with minimal performance penalty. With their
compact 64 pin package, low power consumption, various 32-bit timers, 4- channel 10-bit ADC,
USB PORT,PWM channels and 46 GPIO lines with up to 9 external interrupt pins these

microcontrollers are particularly suitable for industrial control, medical systems, access control
and point-of-sale. With a wide range of serial communications interfaces, they are also very well

suited for communication gateways, protocol converters and embedded soft modems as well as
many other general-purpose applications.
In this project we are using LPC2148, Temperature sensor, Humidity sensor,
Dry/wet sensor to detect the soil moisture condition automatically and 16X2 LCD is used to
display their values with the help of in built Analog to digital converter and the people can
access the information of sensors with the help of simple SMSs by using GSM technology.
This project uses two power supplies, one is regulated 5V for modules and other one is
3.3V for LPC2148. 7805 three terminal voltage regulator is used for voltage regulation. Bridge
type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down
transformer.
