Claim:
1. A portable electronic device comprising; a housing, a chemical sensor sensitive to a concentration value of a component in a sample of air, said chemical sensor being configured and structured to perform a chemical measurement supplying results indicative of said concentration value, a chemical sensor processing unit connected to said chemical sensor, and at least one contextual sensor not including chemical, temperature and humidity sensors, wherein said chemical sensor is integrated into said housing, wherein said at least one contextual sensor is arranged within said housing and/or configured and structured to communicate directly or indirectly with the portable electronic device, wherein said portable electronic device is configured and structured to link an output from said at least one contextual sensor to a local and/or remote interpretation processor, which interpretation processor is configured and structured to generate a constraint or correlation set for restricting interpretations of said chemical measurement results, wherein said portable electronic device is configured and structured to transfer said constraint or correlation set from said local and/or remote interpretation processor to the chemical sensor processing unit, wherein said chemical sensor processing unit is configured to determine said concentration value of said component using said chemical measurement, and using said constraint or correlation set to restrict interpretations of said chemical measurement results by one or more of altering a result of said chemical measurement to match the constraints and correlations as imposed by the input from the interpretation processor or removing uncertainties or false measurements from the results of the chemical measurement, and wherein said interpretation processor is configured and structured to convert inputs as provided by the one or more contextual sensors into the constraint or correlation set including a constraint vector representing a known response or signature or emission profile of the chemical sensor in the presence of one of an object, sound, location information identified from the inputs provided by the one or more contextual sensors.
