This document summarizes an electronics project to modernize Indian agriculture using renewable solar energy. A team of students designed a smart irrigation system controlled by an ARM7 microcontroller that detects soil moisture and water levels. It uses a light dependent resistor to track the sun for maximum solar panel efficiency. Sensors communicate with a farmer's mobile via GSM to operate in auto or manual mode. The system aims to save water and reduce costs by pumping only when needed using solar power, addressing issues of unreliable electricity in rural areas.

3. Modernisation of Indian Agriculture

4. Problem
• Rural areas get variable power supply
• Farmers get 5-6 hours of electrical power a day
• They pump when power is available rather than
when the crop need it
• This leads to water waste and adverse impact on
crops
• Diesel pumps have high operating cost due to
increasing oil prices

6. Objective
• Using renewable energy I,e
solar.
• To save water

7. • The system will detect day and night using LDR(light dependent resistor), for
solar power utilization and storage
• Moister sensor, Dry null(water level) sensor are used to sense the moister level
of soil and water level in water storage tank
• Stepper motor is used to drive solar panel for tracking the maximum intensity
of light
• GSM is used for mobile communication between farmer and arm7 lpc2148
computing system
• There are two modes used to operate the system they are Auto mode and
Manual mode
• Three phase power and solar power is used as supply power input to the
system

• Lm317
• Battery 12v/1.3A
• Stepper motor
• Dry null sensor
• Solar panel
• LDR
• Relay
• LCD
• Toggle switches
• Adapter
• Switches(micros)

12. Software specification

13. NOTE:
 One of the most important key feature of
this system is that “solar panel is not fixed at
one place” it varies position depending on
the maximum intensity of light(solar
tracking).Because of less number of panel
installment due to solar tracking, this
system will not occupy more agricultural
land

14. Advantages
• When power is not available, this system is very
helpful for the farmers to depend on solar power.
• Energy source is renewable as well easily available.
• Reduced man power.
• Saves water and time.
• Compact system.
• Protection of Water Pumps during low water levels
• Long life, easy and low maintenance, and efficient

16. Applications

o Gardens
o Forests
o Parks
o Fountain
o Water Storage
