Project Scope
Agriculture is the most important and worshipped
occupation in the world.
Smart Irrigation helps to the development of agricultural
country.
Water is main resource for Agriculture. Irrigation is one
method to supply water.
In the irrigation process people are wasting water more by
missing the timings.
So to save water and time we have a excellent method called
Smart irrigation system.
4. 4
Problem Statement
Irrigation is the most significant cultural practice and most
labor intensive task in daily agriculture operation.
Manual irrigation system depends on the observation of the
farmer who decides when and how much water flow through
channels should be started.
So, knowing when and how much to water are the two
important aspects of irrigation.
5. 5
Project description
The proposed project is about a device that can remotely
control over internet the water flow to the plant that can be
used by the farmer.
This project is mainly to detect, measure and record the
temperature, and the soil humidity.
These records will be processed by a microcontroller based
on plant require and will be sent over internet to a cloud
system.
6. 6
Project description
Based on actual values of temperature, soil humidity and
plant requirement the water pump will be turned on or off.
A level sensor is used to detect the water level in the tank, if
the water level is at minimum value the microcontroller start
the water pump and when the level is at its maximum the
water pump is stopped.
Also, we propose a manual mode for irrigation based on
sensors value, the farmer can turn on or off the water pump.

Project Benefits
There are diverse benefits associated with IoT systems in
irrigation and some of them might be considered as:
overall water consumption reduction,
high cost-efficiency,
high performance efficiency,
lesser energy consumption,
lesser wastage of crops,
and more...

13. Components: ESP32
ESP32 has Xtensa® Dual-Core 32-bit LX6 microprocessors,
which runs up to 600 DMIPS.
The ESP32 will run on breakout boards and modules
from 160Mhz upto 240MHz .
That is very good speed for anything that requires a
microcontroller with connectivity options.

15. Components: Soil moisture
sensor
Soil moisture sensors typically refer to sensors that estimate
volumetric water content.
A typical soil moisture sensor consists of two parts:
The Probe: . It acts as a variable resistor, with resistance
varying according to soil moisture.
The Module: Generates an output voltage based on the
resistance of the probe, which is available at an Analog
Output (AO) pin.

16. Components: Soil moisture
sensor
The soil moisture sensor operates in a straight forward manner.
The fork-shaped probe with two exposed conductors acts as a
variable resistor whose resistance varies with the soil’s
moisture content.
16
16
This resistance varies inversely
with soil moisture:
The more water in the soil, the
better the conductivity and the
lower the resistance.
The less water in the soil, the lower
the conductivity and thus the higher
the resistance.
17. Components: Temperature
sensor
DS18B20 Waterproof Temperature Sensor is a digital sensor
which can reach the digital data resolution up to 12 bits and has
±0.5°C accuracy from -10°C to +85°C.
It includes an analog-to-digital converter to convert the analog
signal to the digital output with the resolution up to 12 bits.

18. Components: Water level
sensor
The water level sensor is a device that measures the liquid level
in a fixed container that is too high or too low.
According to the method of measuring the liquid level, it can
be divided into two types:
Contact type,
Non-contact type.

19. Components: Water level
sensor
The water level sensor module has the following features and
specifications:
Operating Voltage: 3.3V to 5V DC
Operating Current: 15mA
Output Digital - 0V to 5V, Adjustable trigger level
Output Analog - 0V to 5V
LEDs indicating output and power

20. Components: LCD
A 20x4 LCD means it can display 20 characters per line and
there are 4 such lines.
I2C LCD display has total of 4 pins are:
SDA is the serial data pin
SCL is the clock pin.
The rest 2 pins for power supply (Vcc and ground).

21. Components: Water pump
12 Volt water pump is a dc electric water pump motor that
powered by a 12V direct current power supply.
It use centrifugal force that generated by high speed rotated
impeller to booster, transfer, lift or circulate liquids like water,
oil, coolant etc.

22. Used Components:
Solenoid Valve
A solenoid has an electromagnetically inductive coil (A)
around an iron core at the center called the plunger
(E).
At rest, it can be normally open (NO) or normally
closed (NC).
In the de-energized state, a normally open valve is
open and a normally closed valve is closed.

23. Components: 5V Relay
The 5V relay module can be used to control a load such as a
lighting system, motor, or solenoid.
It can also be used to switch AC or DC voltages.
The maximum voltage and current that the 5V relay module
can control is dependent on the specifications of the relay.

We have successfully designed a sensor based smart irrigation
system with the capabilities of remote monitoring and
controlling of water usage in the agriculture field using IoT.
The system consists of a microcontroller (Node MCU), sensors
(soil moisture, temperature, water level sensor), and irrigation
of a water pump with a decision-making system.
Sensors are linked to a Wi-Fi module (Node MCU) and are
interdependent to provide increased sensitivity to the irrigation
system.

The data obtained should be uploaded to the cloud (Blynk) and
will be presented in the form of graphs accessible via the
website or phone application.
This IoT based smart irrigation system uses minimum human
efforts and permits the user to monitor and control the wet of
the soil to the crop in an efficient and economic way.
It can also:
improve irrigation ways,
increase productivity,
ensure effective uses of restricted resources,
decrease implementation and maintenance
