Automated Weather Observation System
MyAWOS is an automated weather observation system, free for anyone to use. MyAWOS uses can use a NIST certified weather system or a generic weather station.
The system requires a Raspberry Pi, a Aviation Radio, a Weather Station and a relay. So far support for Yaesu and Icom radios, Davis and Ecowitt weather stations.
The best part about MyAWOS is that you can change the code to how you would like. For example - Johann in Munich has set a number of clicks to turn on an off a traffic light at his air field.

How does it work
A local weather station is used. The Raspberry Pi pulls the weather information periodically from the weather station. It converts the weather into an audio file. This can be done in computer generated voice in multiple languages or you can use your own voice. The radio is listening for a number of clicks, which can be configurable. Once it determines the appropriate number of clicks have occurred it will transmit the weather over the radio.
You can configure multiple actions for the number of clicks. For example - if you wanted to just do a wind check you could make that three clicks and full weather five clicks.
