+1

My favorite combo is to use the Rpi UART with a nano arduino that has 8 ADCs @ 10bit and you can get them for like $5. I like to make the ardiuno dumb with a modbus slave. The combination with the UART/MODBUS is extremely reliable. You can also pump it out to tcp with the mbusd utility.

Just some thoughts

You might avoid the ADC chip and instead use an Arduino.  Some Arduino's give an 8 channel ADC at 10 bits resolution.   https://www.arduino.cc/en/Tutorial/Foundations/AnalogInputPins
