The standardized conductivity is the conductance at a given Cell Constant: k = K * G or k = K / R Electrical conductivity is also sensitive to temperature change, and gradually increases in a metallic conductor as the temperature is lowered. Insert the TDS probe into the water and check the Serial Monitor. So somewhere in your project there must be another lead connected to that material. dataPin averageVoltage=AnalogAverage*(float)5000/1024; Serial.print(averageVoltage); //millivolt average,from 0mv to 4995mV, Serial.print(temperature); //current temperature. This is for a very basic conductivity circuit built with a single resistor and an old power cord. 3.After the values are stable, the first point can be calibrated. With the loops on the probe wires, I can use alligator clips to connect the probe to the breadboard. Conductance equals the inverse of resistance mathematically: G = 1/R . receivedBuffer[receivedBufferIndex] = receivedChar. But that's how electricity works. // Always safest to start with a bad value. How to install Libraries in Arduino IDE. Not all processor pins can be used as analog pins. Introduction: How to use DFRobot PH Meter module with an ESP32.
