WebA typical pH probe ideally produces 59.154 mV/pH units at 25°C. This is usually expressed by the Nernst equation as shown below: Where: E = voltage of the hydrogen electrode with unknown activity. a = ±30 mV, zero point tolerance. T = ambient temperature in 25°C. n = 1 at 25°C, valence (number of charges on ion) WebAug 29, 2015 · From the source code I found, voltage maps to pH value. This is the code: pHArray [pHArrayIndex++]=analogRead (SensorPin); if (pHArrayIndex==ArrayLenth)pHArrayIndex=0; voltage = avergearray (pHArray, ArrayLenth)*5.0/1024; pHValue = 3.5*voltage+Offset; samplingTime=millis (); But then the …
