When I try to connect to the sensor from Linux, I should be accessing the correct serial port, but I can't.

The serial device group such as / dev / ttyACM is "dialout" and you cannot access it if your account does not belong to the "dialout" group. To find out which group your account belongs to, please execute with sudo id & lt; account name & gt; If there is no "dialout" in the groups, it does not belong to the "dialout" group, you can add a "dialout" group by running sudo usermod -a -G dialout & lt; account name & gt;
After that, once you log off and log in, it will operate as a member of the "dialout" group, so try connecting to the sensor again.
