I have been spending quite a lot of time with improving the pH calibration function. We need to find the right balance between the speed of the pH change and the moment when the only deviation from the measurement is the analogue & digital noise created by the components. We are able to measure pH with 0.01 precision, which is absurd for use in an aquarium, yet we struggle how to exchange portion of this precision for the calibration function simplification. This is how my desk looks these days.
