This project summary describes an automated plant watering system. It uses sensors to measure soil moisture and temperature. An Arduino microcontroller processes the sensor readings and controls a solenoid valve to water the plants when the soil is dry. The system provides wireless communication through a Zigbee module for remote control. The document outlines the components, circuit diagram, working mechanism, advantages and applications of the automated irrigation system.

2. ACKNOWLEDGEMENT
It is indeed a privilege and opportunity to express my
sincere gratitude to all those who have helped me in
completing this project.
I would really like to thank and acknowledge my mentor
Mrs. Hema N for her help and support throughout the
semester in the making of the project. Her esteemed
individual guidance and helpful suggestions for improving the
presentation of this project are certainly invaluable. I would
further like to express my sense of indebtedness to her for
redressing errors in the project whenever I was unable to.
I am especially grateful to Dr. Saurabh Raina and Mr.
Pawan Upadhyay for taking out time to evaluate my project.

5. INTRODUCTION
•In the world of advance electronics, life of human beings
should be simpler. Hence to make life more simpler and
convenient, we have made “AUTOMATED WATERING
SYSTEM
•A model of controlling irrigation facilities to help millions of
people. This model uses sensor with microcontroller to make
a smart switching mechanism of Water using sensors from
any part of field by sensing the moisture present in the soil.

9. Arduino is an open-source electronics
prototyping platform based on flexible, easy-to-
use hardware and software.
Arduino can sense the environment by receiving
input from a variety of sensors and can affect its
surroundings by controlling lights, motors, and
other actuators. The microcontroller on the
board is programmed using the Arduino
programming language (based on Wiring ) and
the Arduino development environment (based
on Processing ). It has an ATmega AT328
microcontroller that has a pre-installed
bootloader, so one can download code to the
board using only a USB-serial connection.
Arduino projects can be stand-alone or they can
communicate with software running on a
computer.

10. Merits
1) Highly sensitive, reliable, low cost project.
2) Works according to the soil condition.
3) Complete elimination of the man power.
4) System can be switched into manual mode when
required.

11. 1) Irrigation in fields.
2) Irrigation in Garden, Parks.
3) Very useful for people who do not have time to
water their plants because of busy life schedule.
4)The project is very economical in terms of cost and
power
Significance of the project

12. MOISTURE SENSOR

13. The general idea is that we want two probes --
metal rods, kept about equal distance apart, that
we can bury in the soil. We will need an
electrically non-conductive material to help keep
the rods in their fixed position. And we will also
want the probes to be insulated everywhere
except where we want to take a reading.
It uses the two probes to pass current through
the soil, and then we read that resistance to get
the moisture level. More water makes the soil
conduct electricity more easily (less resistance),
while dry soil conducts electricity more poorly
(more resistance).
Moisture Sensor Working

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