|
- Custom Perl scripts to communicate with the Vantage Pro2, write to the MySQL database, and upload weather observations to Wunderground and CWOP.
|
|
|
| How does it ALL Work? |
|
|
- The weather station sends real-time data
to the server every 2.5 seconds. These real-time obsevations are also relayed to Wunderground. Once every minute the average readings are written to the MySQL database.
|
|
- Every 5 minutes the server reads the database and sends the average readings for the past five minutes to CWOP.
|
|
- When you visit the LA LAKE web page, the server reads the MySQL database and returns the mose recent observation data. PHP is used to dynamically create the web page that you see.
|
|
- When you request a graph, the server reads the MySQL database and returns the the appropriate data based on your request
. PHP and JpGraph are used to dynamically create both the web page and
the graph.
