In order to allow a non-sudoer to read data from the sensors connected via USB port, you need to add a rule for udev system.

Similar to the advice from debian udev documentation, create /etc/udev/rules.d/80-persistent-local-usb.rules with the following contents:

KERNEL == "ttyUSB0", MODE = "0777"

Another popular solution:

sudo usermod -a -G dialout $USER # Effect after reboot
