Yes you can send a long string over from the Arduino like @a13.98b200c0.079d346e122.7 and use the VB string functions to select out each sensor value. You might write a function to simplify this
function GetSensorVal(BeginingLetTer,EndingLetter) returns float or whatever
then to get the first value you could just call Val1 = GetSensorVal("c","d") and it would give you 0.079
You really don't need the @. I just used it as the start of the string since I am looking at only one temperature value and it made a good character to use when I was trying to identify the correct com port.
