This document describes an automated solar powered irrigation system that uses energy management. The system allows farmers to remotely operate water pumps for fields using a GSM modem from their mobile phone. It uses a microcontroller, GSM modem, solar panels, pumping motor and LCD display in its design. The system aims to provide irrigation power through renewable solar energy in remote areas without a steady fuel supply. It saves manpower and water while improving agricultural productivity.

3. OBJECTIVE
 This project is mainly related with off-grid application.
 The objective is to supply water to the fields by using solar
power as the main source.
 In this the user can water fields from anywhere by using
GSM technique.

4. EXISTING SYSTEM
 In the existing systems the power generation is carried out by
the conventional energy sources.
 This conventional energy sources causes greenhouse gases
emission which leads to the global warming.

5. PROPOSED SYSTEM
 In the proposed systems the power generation is carried out by
the renewable energy sources.
 Useful in remote locations where a steady fuel supply is not
possible.
 Providing a adequate and quality power to domestic and other
consumers.

7. 8051 MICRO CONTROLLER

8. A micro controller is an integrated on chip with a
processor.
Other support devices like program memory, data
memory, I/O ports, serial communication interface etc
integrated together.
A microcontroller does not require any external
interfacing of support devices.

9. GSM MODEM
 GSM-Global System for Mobile Communications
 A GSM modem is a wireless modem that works with a GSM
wireless network. A wireless modem behaves like a dial-up
modem.

10. MAX 232
 The MAX 232 is an IC.
 converts signals from an RS-232 serial port to signals suitable
for use in TTL compatible digital logic circuits.
 The MAX232 is a dual driver/receiver and typically converts
the RX, TX, CTS and RTS signals.

11. SOLAR PANEL
•Solar panel refers to a photovoltaic module.
•Solar modules use light energy (photons) from
the sun to generate electricity.
•Ranges from 100 to 320 watts.
Photovoltaic cell performs basically 3
operation:
1.The absorption of light, generating
either electron-hole pairs or excitons.
2.The separation of charge carriers of opposite
types.
3.The separate extraction of those
Carriers to an external circuit.

12. PUMPING MOTOR
 A water pump is any device for moving water.
 exists in an enormous variety of styles.
Some uses of water pumps include:
1. Obtaining water from ground wells for drinking, cooking, and other
purposes.
2. Moving water in active solar heating systems.

13. LCD DISPLAY
 Liquid-crystal display - LCD.
 LCD uses the light modulating properties of liquid crystals.
 LCDs are available to display arbitrary , fixed images preset
words, digits, and 7-segment displays as in a digital clock.

14. HARDWARE COMPONENTS
 Micro controller.
 GSM Modem.
 max 232.
 Solar panel.
 Pumping motor.
 Lcd display.

15. SOFT WARE & LANGUAGES
SOFTWARE :
 Keil software.
 Proload / Flash Magic.
 Will pro.
LANGUAGES:
 Embedded c .

16. WORKING OF THE PROJECT:
 This project gives information about off-grid irrigation
system.
 The farmer (user) can water the fields from any place.
 This project uses linear programming.
 Using this system, one can save manpower, as well as
water to improve productivity.

17. ADVANTAGES
 Low cost
 Communicate long distances
 Easily diagnosis the surrounding environment.

18. APPLICATIONS
 Agricultural fields.
 Agriculture research stations.
 Cultivations.
 Nursery plants.
