2. Development of a device for receiving telemetry and sending it to IoT server.
3. Development of an IoT server able to collect data and analyse.
4. Development of an instrument for wind direction mapping.

🚀 Features

1. Getting meteorological data such as:

• Air temperature,
• Atmospheric pressure,
• Air humidity,
• Soil moisture,
• Wind direction,
• Dust value 2.5 PM and 10 PM.

2. Communication between weather stations and base stations using IEEE 802.11 standard.
3. Sending received data to IoT server via GSM communication from base stations.
4. Ability to view data via a graphical interface from any device.
5. IoT server aggregating and analyzing data.
