Hola buenas, necesito ayuda con SIM900 y url compuesta por las variables.

Mi problema es que necesito enviar dentro de la url el valor de las variables, las cuales no son fijas, el ejemplo seria : http..............?hef.Tem=1&luz=2$lon=3...... donde los numeros 1,2 o 3 cambiarian al valor que tenga esa variable en ese momento.
Esto para enviar por 3G.
