I am reading a sensor that returns data CSV with multiple real numbers but my code not reading the numbers. I will like to create a graph

dev = DeviceOpen["Serial", {"COM8", "BaudRate" -> 9600}]
(*This is for windows platform port format.Replace COMx with x been \
the port number and budrate same as in sketch*)

data = {};

int = {};

task = RunScheduledTask[
  If[DeviceExecute[dev, "SerialReadyQ"], 
   Module[{csv, raw}, csv = FromCharacterCode[DeviceReadBuffer[dev]];
    raw = Flatten[Cases[ImportString[csv, "CSV"], {_Real}]];
    volt = ToExpression[raw, TraditionalForm];
    data = Join[data, int];]], 2]

(*Print[Dynamic[int]]

Dynamic[ListLinePlot[data]]*)

Sample of data pritned in serial monitor
