Handson Activity: Build and Test a Conductivity Probe with Arduino Contributed by: SMARTER RET Program, Polytechnic Institute of New York University
I'm building a controller based on a Arduino Mega 2560 and some stackable shields made by myself to manage an marine aquarium.
Believe it or not this circuit will work with the digital IO pins of your Arduino or you can use it with the analog pins to detect the amount of water induced.
The PASPORT Salinity Sensor works with the included Salinity Sensor Probe to measure salinity, conductivity and temperature.
This sketch works because the Arduino pins can be in one of two states, which are electrically very different. Alogrithm for capacitance meter sketch.
