Automatic Plant Watering System

This is a perfect beginner-friendly electronics project that introduces you to sensor input, relay control, and water pump activation using Arduino Uno R3 compatible board. It helps you reduce water waste and keeps your plants green and thriving even when you forget to water them.

🔧 How it Works:

• The soil moisture sensor checks if the soil is dry.

• If moisture is low, Arduino triggers the relay, which turns on the water pump.

• Water flows to the plant until moisture levels are restored.

✅ Features:

• Automatic plant irrigation

• Prevents over-watering and under-watering

• Simple and scalable system for multiple plants

• Ideal for indoor gardens, balcony plants, and DIY school projects

• Fully customizable using Arduino code

📦 Components Needed:

• Arduino Uno R3 compatible board

• Soil Moisture Sensor

• Relay Module (1-channel)

• Mini Submersible Water Pump

• Jumper Wires

• Power Supply / Battery

• Water tubing (optional)
