Smart Irrigation System Project Using Arduino

₨9500

Overview

The Smart Irrigation System using Arduino is an automated watering system that monitors soil moisture levels and controls a water pump accordingly. This project is designed to conserve water, reduce manual effort, and ensure optimal plant health. It is perfect for gardens, farms, greenhouses, and indoor plant care.

By using an Arduino micro controller, a soil moisture sensor, and a relay-controlled water pump, this system automatically waters plants when the soil is dry and stops when the soil reaches the required moisture level. The project can also be enhanced with LCD displays, Bluetooth, or IoT features for remote monitoring.

Description

Components

  • Arduino Uno/Nano – Controls the system logic.
  • Soil Moisture Sensor – Detects soil moisture levels.
  • Relay Module – Switches the water pump ON/OFF.
  • Water Pump – Delivers water to plants.
  • Power Supply – 5V or 12V DC supply.
  • LED Indicators – Show system status.

Working Principle

  1. The soil moisture sensor measures moisture levels in the soil.
  2. If the soil is dry, the Arduino triggers the relay module, turning the water pump ON.
  3. Once the soil reaches the required moisture level, the pump is turned OFF to prevent over watering.
  4. The system repeats this process continuously to maintain optimal soil moisture.
  5. (Optional) Data can be displayed on an LCD screen or sent via Bluetooth/IoT for remote monitoring.
