Chemical sensor in a portable electronic device

A portable electronic device, such as a mobile phone or a tablet, contains a chemical sensor (12) being sensitive to at least one analyte and a trigger sensor (13), such as a humidity sensor, a pressure sensor, a flow sensor or an accelerometer. A signal (RH(t)) supplied by the trigger sensor (13) i...

Beschreibung
Zusammenfassung:	A portable electronic device, such as a mobile phone or a tablet, contains a chemical sensor (12) being sensitive to at least one analyte and a trigger sensor (13), such as a humidity sensor, a pressure sensor, a flow sensor or an accelerometer. A signal (RH(t)) supplied by the trigger sensor (13) is monitored. Subject to the signal (RH(t)) of the trigger sensor (13) or to the signal (CH(t)) of the chemical sensor, a chemical sensor reading is taken for detecting one or more of a presence and a concentration of the at least one analyte in a gas supplied to the chemical sensor (12). By doing so, the chemical sensor reading can be triggered based either on conditions of the environment surrounding the portable device or based on the condition of the chemical sensor itself.
