3. System Design and Methodology
3.1 SYSTEM OVERVIEW:
The proposed system combines several
components. including sensors microcontroller
and actuators To automate the irrigation process
The main components and functions include:
Arduino Uno: A microcontroller board based on
the ATmega328P chip, featuring 14 digital
input/output pins, 6 analog input pins, a USB
connection for power and communication, and a
variety of onboard components such as LEDs, a
reset button, and a power jack
. Relay Module: A device that uses a small control
signal to switch a larger electrical load on or off.
It typically consists of a relay, a coil, and contacts and frequency to power electronic devices
that open or close the circuit. It allows a low-
power signal to control a high-power
circuit.
3.2 Working Mechanism
The system operates in the following steps:
Water motor : A water pump is a device that
increases the pressure of water or other fluids to Data Collection: Soil moisture sensors are

“alternately” (unless you really mean
something that alternates).
Irrigation Trigger: If the soil moisture falls
below the threshold, the relay activates the
water pump to irrigate the soil.
Automatic Shut-Off: The pump stops once
the desired moisture level is achieved,
preventing overwatering.
3.3 Software and Programming
The system is programmed using the Arduino
IDE. Key aspects of the code include:
