pH calibration not storing into memory correctly

[niget2002]

DIscovered that eeprom.write and eeprom.read only stores values from 0-255

switched code over to use eeprom.put and eeprom.get.

Still need to clean up code to remove extraneous Serial.println's that were used during debugging. Also need to remove hard-coded calibration values that were used during testing.

are you still happy with the Ph sensor from DFrobot? are they submerged under wather the whole time? Can you share your library pls to make them work.

I would love to connect them to a PI instead of arduino

[niget2002]

I am. I have two of them. One in the tank and one in the top to measure kalk water.

Not sure this would work with the pi as you have to use an analog input.

My code for the pH is mixed in with the arduino code. I didn't break anything out into libraries.

@niget2002 : My question was more, how long are your PHprobes lasting before you have to buy new ones? Are you happy of the calibration, the result they give back..

[niget2002]

Oh.

I'm not sure how long they'll last. I've only had them since June of last year. I've only had to calibrate them once from what I can tell. I should probably do that again soon. Most probes only last a year. These are supposed to be 'pro' so I'm hopping they last a little longer.
