Why not wrap them all up in a Json formatted string and send.

Job Done.

Yes, Sample all sensor values, wrap them all up in a JSON formatted string and send e.g:

{"Sensor Humidity":"56%","Sensor Lux":"120","Sensor Temp":"24.5"}

Use AdruinoJson Library, It is really good and will allow both creation and parsing of initial string.

Hope this helps
