ISFET pH sensors work by measuring the voltage generated when hydrogen ions in the solution interact with the gate of the transistor. The gate of the transistor is coated with a thin layer of a sensitive material that reacts to changes in pH. When the gate interacts with the hydrogen ions in the solution, a voltage is generated that is proportional to the pH of the solution.
