A security system for a building comprises a pressure sensor and a computer system communicatively coupled with the pressure system. The pressure sensor coupled to a movable portion of a window in the building. The computer system is configured to: receive a first pressure measurement from the pressure sensor; compare the first pressure measurement to a reference pressure measurement; and based on the comparison, detect that the movable portion of the window has moved.

Using pressure sensors in a security system

A microphone package is integrated with a built-in speaker driver. A microphone application-specific integrated circuit (ASIC) and the speaker driver can be directly coupled to an external application processor, eliminating a need for a codec and thus, reducing the size, cost, and/or complexity of a device. In one aspect, the speaker driver and the microphone ASIC are implemented as separate dice mounted on the package substrate. In another aspect, the speaker driver and the microphone ASIC are implemented as stacked die on the package substrate. In yet another aspect, the speaker driver and the microphone ASIC are implemented as a single die on the package substrate.
