I have seen a few posts here regarding TDS but I wanted to see if anyone can guide me in getting TDS from the mentioned probes.
The probes are:
These are used by the very common meter:
These are very accurate and inexpensive meters but I would like to integrate the readings in a larger project. So, my thought is to buy the probes and somehow interface them with the Arduino.
Now, I know that TDS measurement is a complicated issue in of itself and that DM-1 meter is probably doing a lot of cool stuff, but seeing that the probes have 4 wires each (8 total for the dual) does anyone have any clue as to how these are interfaced properly?
Any hints or guidance will be of immense help!
