Next, the multi-gas sensor 100 performs a gas measurement by operating a sensor corresponding to the sensor function selected by the user (S331). For example, any one of a carbon dioxide sensor, a carbon monoxide sensor, an alcohol sensor, and an LPG sensor may be operated. In the case of drinking measurement, the alcohol sensor may operate to measure the alcohol concentration, and in the case of drowsiness measurement, the carbon dioxide sensor may operate to measure the carbon dioxide concentration. At this time, in the case of drinking measurement can be determined whether the concentration exceeds the reference value by measuring the alcohol discharged during breathing. For alcohol measurement, the alcohol sensor of the sensor module 120 may be configured to include an electrode made of platinum, and the alcohol concentration may be measured based on a principle of electrically measuring the degree of attachment of alcohol molecules to the platinum electrode. In addition, various prior art principles for the alcohol sensor may be utilized.

Next, the multi-gas sensor 100 outputs the measured result value through the output means (S341). For example, it is possible to output the measured value in the form of a signal, a message, a voice, a sound, etc. to the above means such as the signal output unit 152, the display unit 154, the warning sound output unit 156, exceeding the allowable value. In one case, the warning sound is output through the alarm output unit 156 or the red signal is flickered through the signal output unit 152 to notify the user. In addition, the measured result value may be displayed on the screen of the navigation 200. For example, the LPG leakage and drinking measurement result values may be displayed.

In another embodiment, the multi-gas sensor 100 may notify the emergency situation by transmitting a predetermined message type to the user or a mobile phone terminal of a specific person related to the user. Therefore, in case of an emergency that can not be handled by the user, it is possible to take appropriate measures according to various emergency situations by informing an emergency situation to a third party.
