Smart Irrigation System

I designed and implemented a Smart Irrigation System that automates watering based on real-time soil moisture levels, reducing water waste and improving irrigation efficiency.

The system uses an Arduino Mega as the main controller, multiple soil moisture sensors to monitor different zones, and relay-controlled solenoid valves and a water pump to manage irrigation automatically. When the moisture level drops below a certain threshold, the sensors send signals to the Arduino Mega, which processes the data and triggers the irrigation system.

➡️ What I Built

✔ Automated irrigation control system

✔ Multi-zone soil moisture monitoring

✔ Relay-based pump and valve control

✔ Intelligent water distribution logic

✔ Scalable smart agriculture solution

➡️ System Overview

• Soil moisture sensors continuously measure moisture levels in different areas

• The Arduino Mega processes sensor data in real time

• When moisture drops below a predefined threshold, irrigation is triggered

• Relays control:

✅Water pump operation

✅Solenoid valve opening/closing for each zone

✅Each zone can be managed independently for efficient water usage

➡️ Key Features

✅Real-time soil moisture monitoring

✅Automatic irrigation control

✅Multi-zone irrigation support

✅ Relay-based control for pumps and solenoid valves

✅ Water-saving and energy-efficient design

✅ Reliable and expandable embedded architecture
