Hello Brian,
I hope you could help me out here please. Thanks in advance.
I have another problem with another DFRobot sensor. This time is the EC probe. I tried to calibrate the probe but somehow it is only giving me zero value.
I have a feeling that the EEPROM has somehow set zero value in the probe memory, as per the pH meter. I wonder if you have the same issue?
I did the EEPROM and EC still 0. Voltage from 0 to 220 after inserting into 1413 calibration solution (voltage changed from 0 to ~220).
