Original Abstract Submitted
a sensor system includes a sensor of a limiting current type that detects an oxygen concentration, and a control device. the control device includes a storage that stores a calibration curve indicating relation between a voltage applied to the sensor and an oxygen ion current, the relation being changed according to the oxygen concentration. the control device is configured to measure the oxygen concentration by applying, to the sensor, a voltage based on the calibration curve and a detection value obtained by performing application of a voltage to the sensor.
