More Information
Summary:A gas sensor and the drive circuit for the sensor are installed within a mobile electronic device. The gas sensor is intermittently heated to an operating temperature for detecting gases and kept at an ambient temperature for other periods. When a sensor of the mobile electronic device detects that the device is placed in a closed space, the heating of the metal oxide semiconductor is halted. When the sensor detects that the mobile electronic device has been taken out from the closed space, the heating of the metal oxide semiconductor is resumed. The poisoning of the gas sensor by siloxanes or the like is prevented.
