Smart-Irrigation-System

💧 Smart Irrigation System (IoT)

An IoT-based Smart Irrigation System developed using Arduino UNO and Embedded C++, designed to monitor soil moisture levels and automate water control.
The system detects soil dryness and autonomously activates the water pump, ensuring efficient irrigation and promoting sustainable water management in agriculture.

🌱 Project Overview

The system optimizes agricultural irrigation by integrating sensors and automation.
When the soil moisture level drops below a defined threshold:

• The Arduino UNO receives input from the soil moisture sensor.
• The relay module triggers the water pump automatically.
• Once the soil reaches sufficient moisture, the pump shuts off. This minimizes water wastage and improves crop growth efficiency.

🧩 Components Used

• Arduino UNO – Microcontroller for processing sensor input and controlling the pump
• Soil Moisture Sensor – Detects soil wetness/dryness
• Relay Module – Controls the water pump based on Arduino signal
• Water Pump – Activates irrigation automatically
• Power Supply & Jumper Wires – Provides connectivity and operation

💻 Software & Tools

• Embedded C++ – Programming logic for automation
• Arduino IDE – Code development and hardware interfacing
• Serial Monitor – Real-time observation of sensor readings

⚙️ Working Principle

1. The soil moisture sensor continuously monitors soil humidity.
2. When the sensor detects dryness (below threshold), it sends an analog signal to the Arduino.
3. Arduino triggers the relay to turn ON the water pump.
4. Once optimal moisture is restored, Arduino turns OFF the pump automatically.
5. The process repeats continuously, ensuring minimal water usage.
