🌿 Smart Plant Monitoring System

🔍 Overview

• The Smart Plant Monitoring System is an embedded IoT solution designed to monitor environmental factors affecting plant health.

• Powered by the ESP32 microcontroller, it integrates multiple sensors for real-time monitoring.

• Displays readings on a 128x64 OLED screen with mood emojis 🙂😐😟 to indicate plant status.

• Alerts users when:

  • Soil moisture is low
  • Temperature or humidity are out of range
  • Ambient light is insufficient

• Provides Serial Monitor output for debugging and advanced monitoring.

• Built using Arduino IDE for easy accessibility and customization.

• Open-source and extendable for advanced features such as:

  • Automatic watering
  • Remote IoT notifications
  • Cloud integration
