A Microcontroller based digital pH meter was designed and developed to measure the value of pH (acidity or alkalinity) for any type of solution. Two op-amps of high input impedance and low output impedance were used to design the pH meter: one is used as a buffer and the other as a summing amplifier. The output of the summing amplifier is connected to the microcontroller as an input. The pH val...
