This is to certify that this project and thesis entitled "AUTOMATIC IRRIGATION SYSTEM" was made by the following students under my direct supervision and this work was carried out by them in the laboratories of the Department of Electrical and Electronic Engineering at the Faculty of Engineering. of Daffodil International University in partial fulfillment of the requirements for the Bachelor of Science degree in Electrical and Electronic Engineering. We would then like to take this opportunity to express our appreciation and gratitude to our project and thesis supervisor Saikat Basak, Senior Lecturer, Department of EEE for his dedication in supporting, motivating and guiding us through this project. In addition, we would like to thank all our friends for sharing their knowledge; information and helping us to make this project successful.
To our beloved family, we would like to extend our deepest love and gratitude for their great support and also for their inspiration and encouragement during our studies in this University. Agriculture is a source of livelihood for the majority of Bangladesh and has a major impact on the country's economy. If the farmer is far from the agricultural land he will not notice the current conditions.

- Summary
Information on the various didactic and types of soil moisture grid cuttings was obtained from the Ontario Ministry of agronomic, Food and Rural Affairs website and various grid jack artisans and vendors. Depending on the types of plants to be watered, the required soil moisture for improvement and protection varies. This project is organized as follows Chapter-1 Introduction of the project Chapter-2 Reviewing the literature Chapter-3 Theoretical model.
In this chapter we discussed about our project Automatic irrigation system where we briefly discuss about the project. In the last part of this chapter, we discuss about our object, the future scope of the work, methodology and project overview.

- Summary
Drip irrigation requires about half the water required for sprinkler or surface irrigation. Ar duino can be used to create interactive items, taking input from a varied collection of switches or sensors and controlling an assortment of lights, motors, and other physical outputs. Arduino activities can be standalone, or they can be associated with programs running on your machine.
The plate can be assembled by hand or purchased fully assembled; The open source IDE can be downloaded for free. The cheapest version of the Arduino module can be assembled by hand and even the pre-assembled Arduino modules cost less than 417 Taka.. Cross-platform - The Arduino software (IDE) runs on Windows, Macintosh OSX and Linux operating systems.
Simple, clear programming environment - The Arduino software (IDE) is easy to use for beginners, yet flexible enough for advanced users to take advantage of as well. For teachers, it is conveniently based on the Processing programming environment, so students learning to program in that environment will be familiar with how the Arduino IDE works. Here we use Arduino IDE 1.8.1.. Open Source and Extensible Software - The Arduino software is published as open source tools, available for extension by experienced programmers.
The language can be extended through C++ libraries, and people who want to understand the technical details can make the leap from Arduino to the AVR C programming language on which it is based. Open source and expandable hardware - Arduino board plans are released under a Creative Commons license, so experienced circuit designers can make their own version of the module, expanding and improving it. Even relatively inexperienced users can build the breadboard version of the module in order to understand how it works and save money.[1].
Soil Resistivity: Measuring how strongly the soil resists the flow of electricity between two electrodes can be used to determine soil moisture content. Galvanic cell: The amount of water present can be determined based on the voltage it produces because water acts as an electrolyte and produces electricity. American scientist Joseph Henry is often credited with inventing a relay in 1835 in order to improve upon his version of the electric telegraph previously developed in 1831.

- Working procedure
- Summary
A liquid crystal display (LCD) is used to display the humidity transmitted through the humidity sensor. Arduino Nano is used to control the whole process, LCD is used to display humidity level and water pump status. We place the humidity sensor in the soil, it detects the moisture from the soil and sends analog information to the Arduino. Now the Arduino receives the analog signal and processes and checks the status and decides to ON or OFF the pump, at the same time calculates the signal and then sends the calculated data to the LCD.

- Summary
It is a microcontroller board based on ATmega328. Here it has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power connector, an ICSP header and a reset button. It has everything needed to restore the microcontroller; just connect it to a computer with a USB cable or supply it with an AC-to-DC adapter or battery to be opened. Here it has 14 digital pins on the Nano that can be used as input or output, using pin Mode, digital Write and digital Read functions.
These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. From the direct gravimetric measurement of free soil moisture asserting the removal, drying and weighing of a sample, soil moisture sensors measure volumetric water content in a circular manner using several other soil properties such as electrical resistivity, dielectric constant or interaction with neutrons. , as an indicator of moisture content. It is a brand of strip board, a pre-formed circuit board element of copper strips on an insulating bonded paper board, which was manufactured and promoted in the early 1960s by the Electronics Department of Vero Precision Engineering Ltd (VPE).
In this chapter, we have discussed Arduino Nano and its pin description, humidification sensor and technology, application of humidification sensor, relay module, its hardware function, LCD display with pin description, Varo board, DC power supply and piezo buzzer, water pump, switch, bridge rectifier and voltage regulator.
