This IoT-based weather monitoring system collects real-time meteorological data, including temperature, humidity, and more, using various sensors. It provides users with up-to-the-minute weather updates through a user-friendly interface.
Component Requirements
- Microcontroller: ESP8266
- Sensors:
- Rain Sensor (YL-83)
- Humidity/Temperature Sensor (DHT-11)
- Pressure Sensor (BMP-180)
- LDR Sensor
- Power Supply: Battery
- Cloud Platform: ThingSpeak
- User Interface: Mobile App / Web Dashboard
- Other: Connecting Wires
Block Diagram
The system connects multiple sensors, including the BMP180, DHT11, YL-83, and LDR sensors, to a microcontroller (ESP8266) powered by a battery. Data is transmitted to the ThingSpeak mobile app via cloud integration for real-time visualization.
Working Principle
- Data Collection: Sensors collect real-time data (e.g., temperature, humidity, pressure, wind speed) at regular intervals.
- Data Processing: The microcontroller processes the raw data, formats it, and removes any noise or errors.
- Data Transmission: The processed data is sent to the cloud using Wi-Fi or other protocols like HTTP or MQTT.
- Cloud Storage & Processing: Data is stored in a cloud platform (like ThingSpeak) and can be processed for further insights.
- Data Visualization: Users can view real-time data on a web or mobile app, with visual dashboards showing trends and historical data.
