🌱 Smart Farming Monitoring System

A self-sustaining, solar-powered smart plant care system that monitors soil, water, and environment — all automatically.

---

📖 About

The Smart Farming Monitoring System is an IoT-based automated plant care solution designed to monitor and maintain optimal growing conditions for crops or plants without manual intervention. Powered entirely by solar energy, this system measures soil moisture, temperature, humidity, and water level — then automatically controls irrigation and sends real-time alerts to the farmer's device.

Developed as an academic project focused on sustainable agriculture through smart technology.
