ABSTRACT:
An ion-based triple sensor is disclosed. The ion-based triple sensor may include an ion sensing unit, configured to measure an ionic current intensity, a pressure sensing unit, configured to measure a pressure, and a temperature sensing unit, configured to measure a temperature. The ion-based triple sensor may further include a signal processing unit coupled to the ion sensing unit, the pressure sensing unit and the temperature sensing unit. The signal processing unit may include a filtering component, configured to filter at least one of the ion, pressure and temperature measurements, and a data acquisition component, configured to sample the filtered measurements and communicate the samples to a controller.
