IoT Based Smart Irrigation System Using Solar Power

IoT Based Smart Irrigation System Using Solar Power

This project presents an IoT Based Smart Irrigation System powered by solar energy, designed to automate and optimize water usage in agricultural and gardening applications. The system integrates renewable energy, embedded electronics, and smart sensing to provide an efficient, eco-friendly irrigation solution.

The setup is neatly arranged on a white base platform with a clean white background, giving it a professional and commercial-grade appearance. At the top-left corner, a compact ENGINEER’S BUTTY LAB BD logo is placed, scaled to be three times smaller than the main components to ensure branding without visual clutter.

System Overview

The system uses a solar panel as its primary power source, charging a rechargeable battery pack that ensures continuous operation even during low sunlight conditions. An IoT-enabled microcontroller processes sensor data and controls irrigation actions automatically.

Key Components Visible

• Solar Panel – Supplies renewable power to the system

• Rechargeable Battery Pack – Stores energy for uninterrupted operation

• Microcontroller Unit – Acts as the brain of the system

• Soil Moisture Sensor – Detects moisture level of the soil

• Relay Module – Controls the water pump operation

• LCD Display – Shows real-time system status and sensor readings

• Water Tank & Irrigation Area Model – Demonstrates real-world irrigation flow

All components are precisely mounted, wired, and labeled, ensuring clarity for demonstration, academic evaluation, and customer presentation.

Working Principle

When the soil moisture level drops below a predefined threshold, the sensor sends data to the microcontroller. Based on this input, the controller activates the relay to turn on the water pump, supplying water to the plants. Once sufficient moisture is detected, the pump automatically turns off. System data can be monitored remotely through IoT integration.
