🧊 Smart Fridge Monitoring System

A modern Smart Fridge Web Application built using React (Vite) and Tailwind CSS, integrated with cloud data from ThingSpeak.

This system allows users to monitor real-time fridge conditions like temperature, humidity, and door status, while also managing food items and detecting spoilage.

🚀 Features

🌐 Cloud Integration

• Connects to ThingSpeak using:

  • Read API Key
  • Channel ID

• Fetches real-time sensor data from cloud

🌡️ Live Monitoring

• Field 1 → Temperature
• Field 2 → Humidity
• Field 3 → Door Status (Open/Close)

🧾 Inventory Management

• Add food items inside the fridge
• View list of stored items

⚠️ Spoilage Detection

• Detects food spoilage based on general predefined data
• Shows warning alerts for expiring/spoiled items
• ⚡ Optimized for testing: detects warning for a single item within seconds

---

🛠️ Tech Stack

• Frontend: React.js (Vite)
• Styling: Tailwind CSS
• Cloud: ThingSpeak API
• Language: JavaScript (ES6+)

📡 How It Works

1. User enters:

   • ThingSpeak Read API Key
   • Channel ID

2. App connects to the cloud and fetches:

   • Temperature
   • Humidity
   • Door status

3. Sensor data is displayed on the dashboard in real-time

4. User can:

   • Add food items
   • Monitor their status

5. System checks spoilage conditions and gives alerts
