    • A gas sensor control device for controlling a gas sensor, the gas sensor including a gas sensor element that includes a cell including a pair of electrodes and a solid electrolyte, the gas sensor control device including a circuit board connectable to the gas sensor. The circuit board has mounted thereon a voltage control unit mounted on the circuit board and configured to control a voltage developed across a pair of electrodes of the cell to a constant voltage; a temperature detecting unit mounted on the circuit board and configured to detect a temperature of the circuit board; and a voltage correcting unit mounted on the circuit board and configured to apply a correction voltage to the voltage control unit compensating for a temperature-dependent variation in the constant voltage based on the temperature detected by the temperature detecting unit.
