Project Description:

The IoT Weather LED Display is a smart device that fetches real-time weather data from online APIs and displays it on an LED matrix or 16x2/20x4 LCD display. It can show temperature, humidity, weather condition (sunny, rainy, cloudy), and more. The system is ideal for homes, schools, public places, or agricultural settings where quick weather insights are essential.

This project combines IoT, cloud APIs, and hardware display to create a live ambient information system.

Technologies Used:

• Backend: Node.js / PHP / Java (for API handling and connectivity)

• Frontend (Optional Dashboard): HTML, CSS, Bootstrap, JavaScript

• IoT Components:

  • Microcontroller: NodeMCU (ESP8266) / ESP32

  • Display: LED Matrix / OLED / LCD 16x2 / 20x4

  • Connectivity: Wi-Fi via ESP8266

• APIs: OpenWeatherMap, WeatherAPI, etc.

Core Features:

1. Live Weather Data Fetching:

   • Uses REST API to fetch current weather based on location (city name or GPS).

   • Retrieves temperature, humidity, and description (e.g., "Light Rain").

2. LED/LCD Display:

   • Continuously scrolls or updates weather info.

   • Icons/indicators for rain, sun, cloud, etc.

3. Automatic Updates:

   • Periodically refreshes every 5–10 minutes.

4. Admin Configuration (via Web Page):

   • Set location, units (°C/°F), update interval, and brightness.

5. Power Efficient Operation:

   • Sleep modes in microcontroller to save energy when idle.
