This document describes a smart irrigation system created by students to automatically water crops based on soil moisture levels. The system uses an Arduino board, soil moisture sensors, a servo motor, water pump, and relay module. It measures the moisture levels of two different plant beds and activates the water pump when the soil is dry to irrigate the plants until the desired moisture level is reached. The system aims to reduce manual labor, conserve water usage, and improve crop yields through real-time soil monitoring and controlled watering.

4. INTRODUCTION
• Irrigation is the artificial application of water to the land
or soil to assist in the growing of agricultural crops.
• Air moisture, air humidity, temperature and water level in
the soil are wirelessly transmitted using wireless
technology for better production.
• To make the farming work easily, the automatic irrigation
system is created .

5. objectives
• Reduce the manpower & conserve the water
• Real time sensing and control
• To get the output of soil water sensor and provide
water to crop
• To observe other parameters for better yield

7. resources and its working
•Arduino Uno
•Servo motor
•Soil moisture sensor
•Mini water pump
•Jumper wires.
•Relay module
•Breadboard

8. Arduino UNO
8
• The Arduino UNO is the brain of this whole
project.
• This project uses Arduino Uno to controls the
motor.
• The Arduino Board is programmed using the
Arduino IDE software.

9. servo motOr
•A Servo Motor is a small device that has an output shaft.
•This shaft can be positioned to specific angular positions
by sending the servo a coded signal.
•As long as the coded signal exists on the input line, the
servo will maintain the angular position of the shaft

10. Soil moisture sensor
10
•The humidity sensor is used to measure the water
content (moisture) of the soil.
• This sensor reminds the user to irrigate their plants
and also controls the moisture content of the soil.

11. 11
Mini water pump
•For this study a water pump is required, which must
be DC, 12V. The DC motor is the commonly used
motor and has DC power distribution systems

12. Relay module
12
• A relay is an electrical main voltage switch. This means
that it can be turned on or off, letting the current flow or
not. Controlling a relay with Arduino is as simple as
controlling an output like a motor .

13. Jumper wire
• A jump cable is used to connect the test plate, the prototype
or the internal circuit with other non-joined instruments.
BREADBOARD
13
•Breadboard is used to
connect the components
AND plan complete the
circuit .

14. WORKING
 This project uses Arduino Uno to controls
the motor. The Arduino Board is
programmed using the Arduino IDE
software.
 The moisture sensor measures the level
of moisture in the soil and sends the
signal to the Arduino if watering is
required.
 The motor/water pump supplies water to
the plants until the desired moisture level
is reached.

15. Arduino IDE Software
The Arduino Integrated Development
Environment (IDE) is a cross-platform application
(for Windows, MacOS, Linux) written in the Java
programming language. It is used to write in the
java programming language. It is used to write
and load programs on the Arduino board. The
source code for the IDE is published under the
GNU General Public License, version 2.
