The presentation provides a comprehensive overview of Automatic Weather Stations (AWS).

1. Introduction to Automatic Weather Stations Automatic weather stations are crucial for collecting accurate weather data. They provide valuable insights for weather forecasting, climate monitoring, and agricultural applications. by Ahmed Sharaf

2. Components of an Automatic Weather Station Sensors Sensors measure various weather parameters, including temperature, humidity, wind speed, and rainfall. Temperature Sensor Humidity Sensor Anemometer Rain Gauge Data Logger The data logger collects data from the sensors, stores it, and transmits it to a remote location. Microcontroller Memory Power Supply Communication System A communication system allows the data logger to send data to a remote server or user interface. Wireless Modem Cellular Network Satellite Link

3. Arduino as the Microcontroller Affordable Arduino boards are relatively inexpensive compared to other microcontroller options. Easy to Program Arduino's user-friendly programming language and extensive online resources make it easy for beginners to learn and use. Versatile Arduino boards can be used for a wide range of projects, including weather stations, robotics, and home automation. Open-Source The Arduino platform is open-source, meaning that the hardware designs and software are freely available for anyone to use and modify.

4. Sensors for Weather Monitoring Sensor Type Parameter Measured Measurement Unit Temperature Sensor Temperature Degrees Celsius (°C) or Fahrenheit (°F) Humidity Sensor Humidity Percentage (%) Anemometer Wind Speed Meters per second (m/s) or kilometers per hour (km/h) Rain Gauge Rainfall Millimeters (mm) or inches (in) Barometer Atmospheric Pressure HectoPascals (hPa) or millibars (mbar)

5. Data Acquisition and Processing Data Acquisition Sensors collect data from the environment. Data Conversion The Arduino converts the sensor readings into a digital format. Data Storage The Arduino stores the converted data in its memory. Data Processing The Arduino can perform basic calculations and data analysis.

6. Wireless Communication and Data Transmission 1 Cellular Network Using a cellular modem, the weather station can transmit data over a cellular network. 2 Wi-Fi Network If Wi-Fi is available, the weather station can connect to a local Wi-Fi network and send data. 3 Satellite Link For remote locations, satellite communication provides reliable data transmission. 4 Radio Frequency Using radio frequency transceivers, the weather station can transmit data to a nearby receiver.

7. Enclosure and Weatherproofing 1 Protection The enclosure protects the weather station's components from harsh weather conditions. 2 Weatherproofing The enclosure is designed to withstand rain, snow, wind, and extreme temperatures. 3 Ventilation The enclosure provides adequate ventilation to prevent overheating and moisture buildup. 4 Maintenance The enclosure should be designed for easy access for maintenance and repairs.

8. Data Visualization and Monitoring Graphs and Charts Visualize weather data trends over time using graphs and charts. Interactive Maps Display weather data on a map to show spatial variations. Alerts and Notifications Set up alerts to notify users of extreme weather conditions. Data Analysis Analyze weather data to identify patterns and trends.
