1. A subsea housing assembly, comprising: a subsea housing, the subsea housing including:
a first housing portion, the first housing portion including a first electrical connection configured to receive data communication of sensor readings, and
a second housing portion, the second housing portion including a second electrical connection for data communication;
a wall to provide separation between the first housing portion and the second housing portion of the subsea housing; and
an inductive coupler including a first coupling section disposed in the first housing portion and a second coupling section disposed in the second housing portion, the inductive coupler being configured to provide inductive coupling across the wall to provide at least a data communication between the first electrical connection in the first housing portion and the second electrical connection in the second housing portion, wherein the first housing portion includes a first chamber, the first chamber including one of a pressure resistant chamber or a pressure compensated chamber, and the second housing portion includes a second chamber, the second chamber including one of a pressure resistant chamber or a pressure compensated chamber;
wherein the first coupling section includes a first coil positioned along a central axis of the first housing portion and the second coupling section includes a second coil, the first and second coils being arranged on opposite sides of the wall and the first and second coils being arranged substantially coaxial and wherein the wall is curved and intersects the central axis;
wherein the second chamber is pressure balanced against an ambient pressure; and
wherein the second housing portion is connected to a subsea cable in form of a medium filled hose, the second chamber being pressure compensated via the medium filled hose.
