A mobile device comprises a CPU operating a display and other user interface circuitry. Further, it comprises a gas sensor as well as a sensor hub connecting the gas sensor and other sensors to the CPU. In order to save power, the device can be brought into a low-power operating mode, where the CPU is idling or switched-off and the gas sensor itself has a low-power and a high-power operating mode. However, even in this low-power operating mode, the sensor hub still monitors for changes of the signal from the gas sensor and wakes the device up if such a change is detected.
