Along with the increase in indoor activity time of modern people, interest in quarantine and indoor air quality is increasing due to the recent spread of COVID-19. So, there have been many studies investigating the users’ location, behavior and status. Bluetooth, CO2 sensor, radio frequency sensor, and imaging sensing methods employing deep learning methods for determining the occupant’s location have been used. In contrast, established techniques of occupant localization had constraints in residential space, such as privacy violations or terminal installation restrictions. However, in a domestic setting, a pressure sensor is a better option. This study provides a method to recognize an occupant’s location through a pressure sensor matrix. This sensor can be utilized anywhere indoors, where the load operates and has no privacy concerns. The calibrations were conducted on each sensor node to verify the performance of the pressure sensor matrix. It was quantitatively reviewed whether the location of the occupant could be tracked. As a result, the pressure sensor is able to identify the location and state of the occupant.
