This invention relates to methods and apparatus for detecting a fall of a user, especially to methods and apparatus for detecting a fall of a user by using pressure sensors. This invention discloses an apparatus for detecting a fall of a user, and the apparatus comprises first and second pressure sensors configured to obtain first and second data values of atmosphere pressure and intended to be worn on the body of the user, and a processor configured to derive a third data value of atmosphere pressure for determining whether a fall occurs or not from the first and second data values of atmosphere pressure. The first and second pressure sensors are configured in a way such that preset orientations of the first and second pressure sensors are opposite to each other. In this way, the weight of measuring elements comprised in the first and second pressure sensors have opposite effects on the measured atmosphere pressure, and thus (?) the measurement error caused by pressure sensor orientation variation can be reduced or even eliminated.
