BBC Weather Observation component
Easily allows you to collect observed weather metrics for your area using the BBC Weather data service. Supports temperature and humidity, pressure, Wind direction etc for your selected area. Also available are Wind Direction, Wind Speed and Air Pressure but please note these are not always available depending on your selected area. This component is used for data gathering from the internet.
Component Source Code
Please click here to download the component source project: FC_Comp_Source_BBCWeatherObservation.fcfx

Detailed description
No detailed description exists yet for this component
Examples
Here is a basic example to read the observation data and report the Manchester weather information for today and tomorrow, on a graphical display.
The location can be set by adjusting the BBC Weather location property, see the component property tooltips for more information on how to do this.
On an embedded device you would need a TCP/IP component to allow the communications to the BBC server. This then links to the Network Comms component.
