Abstract
A device and a method for determining states of an object to be monitored, such as a window or a door. The measurement values of a plurality of sensors, in particular a magnetometer and an acceleration sensor, are merged and are evaluated together. For the determination of a new state from a group of predefined states, only state transitions that are actually possible are taken into account. State transitions that are not possible or are not allowed are not taken into account.
