2. Introduction
• The project is designed to develop an automatic irrigation system
which switches the pump motor ON/OFF on sensing the moisture
content of the soil.
• The project uses a solar panel coupled to a DC motor to track the
Sun so that maximum sun light is incident upon the panel at any
given time of the day.
• It uses solar energy to operate the system with an auxiliary power
a.c. source.

7. Power Supply
• Supply in Microcontroller is required 5v.
• 5 v dc is fed to microcontroller using 7805 voltage
regulator which convert 12v dc to 5v dc.
• Supply required in motor for tracking purpose is 4v
to 12v.

8. Working of model

9. Components Used
• DC geared motor
• Solar Panel
• 12v battery
• Capacitors
• Resistors
• 8 bit Microcontroller
• 16*2 LCD
• LDR (Light dependent resistor)
• Transistor
• 7805 Voltage Regulator
• Step down Transformer
• Bridge type Rectifier
• Water Pump

10. LIGHT DEPENDENT RESISTOR (LDR)
• A photo resistor or LDR is a resistor whose resistance decreases with
increasing incident light intensity; in other words, it exhibits
photoconductivity.
• It is used in this project to detect day and night as a sensor.

11. DC GEARED MOTOR
• 200RPM Centre Shaft Economy Series DC Motor is high
quality low cost DC geared motor.

12. Capacitors
Disk Ceramics Capacitors-
• Disk Ceramics consist of two metallic
plates separated by a ceramic dielectric
whose area and spacing determines the
capacitance.
• These Capacitors are low cost and suitable
for many applications.
Electrolytic Capacitors-
• Aluminum Electrolytics are the most
common, inexpensive electrolytic available
from all hobby vendors.
• They are made similar to the polyester
films using aluminum electrodes and a
dielectric material rolled into layers to
increase the effective plate area to form
high capacitances in small packages.

13. Microcontroller
Pin Diagram
• AVR ATMEGA8 microcontroller.

14. • AVR is a family of microcontrollers developed by Atmel
beginning in 1996.
• These are modified architecture 8-bit RISC single-chip
microcontrollers.
• AVR was one of the first microcontroller families to use
on-chip flash memory for program storage, as opposed to
one-time programmable ROM, EPROM used by other
microcontrollers at the time.

15. 16*2 LCD
FEATURES
• + 5V power supply
• 1/16 duty cycle

16. Transistor
• A transistor is a semiconductor device used to amplify or switch electronic
signals and electrical power.
• In project ,It is used to amplify the input of moisture sensor.

17. 7805 VOLTAGE REGULATOR
• 78XX series of voltage regulators are used to provide constant XX volts at
output. These are 3 terminal positive voltage regulators employ internal
Current-limiting.

18. ADVANTAGES
• No electricity requirement.
• It uses non-convention energy resourses.
• No complicated circuit.
• Automatic sun tracking for max power use.
• Automatic motor control, hence no man control
is required

19. • It will be used in all type of agriculture.
• It can be used for garden irrigation system.
• Town parks.
• Remote area farming.
Applications

20. Conclusion
• This project is fully automated system.
• Maximum power of solar panel is utilized
because solar tracking is used.
• It is ecofriendly.
• No external power is required.
