Real-time self-calibrating sensor system and method

摘要: A system and method for calibrating a sensor of characteristic monitoring in real time utilizes self-calibration module periodic determination of, compensation for, the IR drop across unwanted resistances cell. current-interrupt switch is used to open circuit either measure using high-frequency (MHz) ADC module, or estimate it through linear regression acquired samples voltage sensor's working reference electrodes (Vmeasured) over time. The then subtracted from closed-circuit value Vmeasured calculate overpotential that exists cell (Vimportant). Vimportant may be further optimized by subtracting open-circuit (Voc) electrodes. values are controlled respective first second control units compensate drop.
