Serial Data Logger V2.0.0

Hello and 早上好,

I am trying to run the data logger V2.0.0, powered remotely via 3x18650 batteries in series. I know that the logger is functioning because it is printing out new CSV files, and I can see these when I connect the datalogger to the computer. But when I open these files, they are empty

I know that the “Gravity” sensors I am using function, because they output data in the serial monitor, in real time.
