a quick hacl to print one value per line
int count = 0;
void loop()
{
if (pH.available() >0)
{
char incharPH = (char)pH.read();
if (inchar =='.') count = 0;
Serial.print(incharPH);
count++;
if (count==3) Serial.println();
}
}
Give this version a try to see if there is a separator between the readings
int count = 0;
void loop()
{
if (pH.available() >0)
{
char incharPH = (char)pH.read();
Serial.print((int) incharPH, DEC);
Serial.print("\t");
Serial.println(incharPH);
}
}
