Project advice : DAQ - instruments

I'm planning to start a new project in witch i will creat a data acquisition system
instruments i have :

  • Geosig-ve53 as a sensor

  • KCPI-3101 as a PCI card

  • Computer

My idea is : the sensor will be conntected to the PCI card, the card receiving signal and the computer visualize and record those data using Python.
Now i'm thinking that this sensor is for Field studies ( seismological studies ) and it would be great if all the instruments can be portable and can have access to realtime data via laptop.
my question is what can a microcontroller has as a role to take this project to the next level ?

I'm new to microcontrolers world but having basics on python.
Thank you.
