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:
- Use an RS485 to UART converter IC to talk to the Pi?
- Or, somehow create a custom python script to interface with their protocol?
Any recommendation would be nice!!!
