An elevator car location sensing system includes at least one first barometric pressure sensor disposed at a sensor position. The first barometric pressure sensor is configured to measure at least one first barometric pressure at the sensor position. An elevator control module is configured to electrically communicate with at least one mobile terminal device that is movable among a plurality of different altitudes. The elevator control module receives a second barometric pressure from the mobile terminal device located at a current altitude, and determines the current altitude based on a comparison between the first barometric pressure and the second barometric pressure.
