Dual pressure sensing module with a shared electrical substrate

An electronic device, comprising:

• an electronic device housing defining an aperture;
• a pressure sensing module coupled to the electronic device housing around the aperture, the pressure sensing module comprising:
• a substrate;
• at least one module housing coupled to the substrate that defines:
• a first chamber connected to the aperture;
• and
• a second chamber separate from the first chamber;
• a first pressure sensing element, electrically coupled to the substrate and disposed in the first chamber, operative to detect an external pressure around the electronic device;
• and
• a second pressure sensing element, electrically coupled to the substrate and disposed in the second chamber, operative to detect an internal pressure within the electronic device housing;
• and
• a seal, positioned between the electronic device housing and the at least one module housing around the first chamber, that
• separates the second chamber from an external environment around the electronic device.

A pressure sensing module for an electronic device, comprising:

• a substrate having a surface and defining a passage through the substrate;
• a housing coupled to the surface to define:
• a first chamber configured to be connected to a first environment via the passage;
• and
• a second chamber configured to be connected to a second environment;
• a first pressure sensing element, coupled to the surface, operative to detect a first pressure of the first environment;
• a second pressure sensing element, coupled to the surface, operative to detect a second pressure of the second environment;
• and
• a water resistant membrane, coupled to the housing and separated from the first pressure sensing element by the first chamber.
