A portable electronic device, such as a mobile phone, and related methods are described using an integrated chemical sensor (12,21), such as metal oxide gas sensor, linked to a chemical sensor processing unit (211,23,25) and being sensitive to the concentration of a component in a sample of air and further including an operating system providing instructions for the control of the portable device, wherein the chemical processing unit uses under operating conditions a first set of instructions and a second set of instructions stored within the portable device, wherein the first set of instructions is part of the operating system level (30,34,36) of instructions and the second set of instructions is part of a user level (38) of instructions with the second set of instructions being linked to the operating system via a plugin interface (372) and wherein the second set of instructions is communicated to the portable device from a remote computing system (29) based on access to measurements and/or operating conditions of the chemical sensor(12,21). The method is particularly suitable for updating sensor settings at the sensor application level through the Internet. |
