No, this is about electrical signals.
If you do not want to modify your sensor board, you could get a level-shifter module and insert that between the Arduino and the sensor module. It is a little silly, but a level-shifter is cheaper than the sensor. You would then need to power the sensor board with 5V. Do not try that without an additional level-shifter. The sensor board would otherwise damage your Arduino.
If you have access to an oscilloscope, I recommend you have a look at the signals to learn. Any cheap old analog oscilloscope would do.
Try to understand the schematic. If you have any specific questions let me know.
I suspect the main issue is U2. To get 3.3V out of it you need to have a voltage that is higher than 3.3V. But if you would just use 5V at Vcc you would get 5V at the IO connector. See how the pins there are connected to the level-shifter and trough the resistors to Vcc.
