****************************************************
For each itteration of the loop test for key, create a variable and set 
its value to the one associated with it. 
These values will be used later on to create the xml file. 
If you have any different sensor values than the ones here, 
you need to create your own test. Format is-
"case ($key == "your_parameter"): //If the key matches returns true
global $your_parameter; //declare parameter as global variable
$your_parameter = $val; //set the value
break;" //Back to the loop
