BBC Weather Forecast component

Easily allows you to collect three day forecasted weather metrics for your area using the BBC Weather data service. Supports Min/Max temperature, Wind Direction, Wind Speed, Visibility, Pressure, Humidty, UV Risk, Pollution and Sun Rise/Set times for your selected area.

Examples

Here is a basic example to read the three day forecast data and report the information on a graphical display.

BBCWeatherForecastDemo


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.
