Multicavity pressure sensor

Abstract:

Aspects of the subject technology relate to an apparatus including multiple cavities disposed adjacent to one another in a housing structure. The apparatus further includes a number of membranes, with each membrane disposed over a cavity to seal the cavity, and a sensor that can sense a deflection of a respective membrane associated with one of the cavities in response to an applied pressure. Each membrane is operable within a respective pressure range, and the applied pressure is within an operating range of the respective membrane.
