Classification: CPC G  H | IPC G

Claim 11:
12. The environmental sensor of claim 11, wherein the analog circuitry comprises an impedance bridge having a first branch with a first pair of impedance elements and a second branch with a second pair of impedance elements,
wherein at least one of the impedance elements is a sensor impedance element configured to transduce an environmental magnitude onto an impedance-related parameter, and at least one of the impedance elements of the first branch and at least one of the impedance elements of the second branch is a reference impedance element,
wherein the impedance bridge presents a first output terminal at the first branch between the impedance elements of the first pair and a second output terminal at the second branch between the impedance elements of the second pair, so as to provide a differential signal which is an analog environmental measurement value of the environmental magnitude,
wherein at least one of the reference impedance elements, or an impedance element in series or in parallel to at least one of the reference impedance elements or sensor impedance elements, is selectably modifiable according to the offset information, so as to apply the offset.
