Custom input for Industrial EC with RS485 protocol

HI everyone,

I’m planning to use this EC sensor: Conductivity, Salinity and TDS Sensor, with Waterproof Aviation Connector - Seeed Studio.
While it has an analog feature, I would like to see if I can create a custom input for the RS485 communication as I want to automate the calibration process.
Some of my initial thoughts:

  1. Use an RS485 to UART converter IC to talk to the Pi?
  2. Or, somehow create a custom python script to interface with their protocol?

Any recommendation would be nice!!!
