This document presents an automatic irrigation system controlled by an Arduino. The system includes soil moisture and temperature sensors to monitor conditions and control a water pump via a relay. The objective is to minimize manual intervention by farmers and prevent over or under irrigation. The block diagram shows the Arduino, sensors, LCD display, relay and water pump. The circuit diagram and components include an Arduino, sensors, LCD, relay module, solar panel and battery. Working steps explain how the sensors send signals to the Arduino to control the relay and pump based on soil moisture and temperature readings. Results show the system automatically supplies water as needed. The conclusion discusses benefits like conserving water, being low cost and useful for farmers and

4. INTRODUCTION
• Irrigation is the artificial application of the land or
soil.
• Knowing when and how much to water is two
important aspects of watering process.
• To make farming works easily, The Automatic
Irrigation is created.
• To impress the farmers for using renewable
energy.

5. OBJECTIVE
• To minimize manual intervention by the farmers.
• To prevent excessive wastage of water & Electricity.
• To protect the plant from instant damage.

11. DISCUSSION & RESULT
 To control Relay with Motor, Arduino used. It is programmed by
Arduino IDE.
 To measure the temperature, The Temperature Sensor
measures and send signal in Arduino.
 To measure the level of soil, The Moisture Sensor senses and
send signal in Arduino.
 Finally The Pump supply the water to the water, until the
desired moisture level is reached.

12. Practical Implementation

13. MERITS
 Highly sensitive
 Works according to the soil condition
 Low cost and reliable circuit
 Complete elimination of manpower
 System can be switched into manual mode whenever required.
 Irrigation in small places too like parks, garden.
 Very useful for common people who do not have time to water their
plant because of busy life schedule.
 This project is very economical in term of cost and power.

14. Conclusion
• In present days especially farmers are facing major problems in
watering their agriculture fields. Because they have no proper idea
about when the power is available so that they the can pump water.
Even after then they need to wait until the field is properly watered,
which makes them to stop other activities.
• Here is an idea which helps not only farmers even for watering
garden also, which senses soil moisture and switches the valve
automatically when the power is on
