Abstract
A method includes collecting, at a building opening, air pressure signals from a pressure sensor and sound signals from a sound sensor. The method also includes sensing pressure peaks occurring in the air pressure signals and sensing sound pulses occurring in the sound signals. A joint occurrence of a pressure peak in the air pressure signals and a sound pulse in the sound signals is indicative of an opening/closing event of the building opening.
