Weather Update Monitoring System via ThingSpeak 

Overview:

The Weather Update Monitoring System is an IoT-based environmental monitoring solution that measures humidity, temperature, and gas levels in real time. The system uploads live sensor data to ThingSpeak for cloud monitoring and data visualization.

If temperature or gas levels exceed the predefined safety threshold, an indicator light automatically turns ON, and the LCD display shows a warning status. This ensures environmental awareness and safety monitoring both locally and remotely.

 Key Features:

1. Real-time monitoring of temperature and humidity.
   
   

2. Gas level detection for safety monitoring.
   
   

3. Automatic light indication when temperature or gas exceeds safe limits.
   
   

4. LCD display shows live sensor readings and system status.
   
   

5. Live data upload to ThingSpeak cloud platform.
   
   

6. Remote monitoring from anywhere via ThingSpeak dashboard.
   
   

7. Graphical visualization of historical sensor data.
   
   

8. Low-cost and energy-efficient IoT-based design.
