Abstract: A pressure sensor integrated onto an electronic circuit substrate. The pressure sensor measures the effect of the ambient air pressure on a characteristic of the pressure sensor that can be translated into a variable pressure measurement. Another embodiment of the pressure sensor is a pressure switch having a set point that can be configured at, or after, the time of installation of the associated circuit substrate.
Abstract: A pressure switch integrated onto an electronic circuit board for sensing when the ambient pressure reaches a specified value. The pressure switch is low profile, reliable and has a set point that can be configured at, or after, the time of installation of the associated circuit board. Further, the pressure switch can contain other electrical components to conserve valuable circuit board real estate and allow the construction of a rugged, protective self-contained electronic pressure switch.
