摘要： A sensor control apparatus including a gas sensor having a sensor element, a housing and a base part formed of a resin. The apparatus includes a heating part and a control part. When the control part determines that a predetermined automatic stop condition has been satisfied, the control part switches from a control for maintaining the temperature of the sensor element at an activating temperature to a control in a stop state for reducing at least one of voltage and current supplied to the heating part so as to set a temperature of the base part to a value equal to or lower than a shape holding temperature of the resin. Also disclosed is a sensor control method for holding a temperature of a sensor element to an activating temperature.

摘要： A sensor control apparatus (3) includes a full-range gas sensor composed of an oxygen concentration detection cell having a pair of electrodes (21, 22) and an oxygen pump cell having a pair of electrodes (19, 20). In an electric circuit section (30), an Ip current flowing between the electrodes (19, 20) is controlled such that an electromotive force Vs produced between the electrodes (21, 22) becomes equal to a reference voltage. The reference voltage is usually set to a first reference voltage. However, when the subject gas is air, the reference voltage is set to a second reference voltage. Humidity of the subject gas is detected on the basis of an error ΔIp between an Ip current detected when the reference voltage is set to the first reference voltage, and an Ip current detected when the reference voltage is set to the second reference voltage.
