For the conductivity meter shown in the photo below, it is a non-NPN sensor for measuring conductivity / impedance.
I am trying to figure out the best method for measuring the output of the sensor using an Arduino.
I am told from the supplier that there is no polarity. I was planning to connect one of the leads through a 10k resistor to an analog input (A0) on my Arduino; and the other lead to 5V?
Without much other information on the sensor, is a 10k resistor a good place to start?
