Abstract

An intrusion sensor for monitoring an entrance to a building to be monitored, the intrusion sensor being situated at the entrance on the inside of the building, includes an acceleration sensor which is configured to detect motions of the intrusion sensor in at least one spatial axis, and in the case of a motion in the at least one axis, to output an acceleration signal, including a surroundings sensor which is configured to detect at least one value of at least one physical variable in the surroundings of the intrusion sensor, and including a plausibility check device, which is configured to carry out a plausibility check of the acceleration signal using the detected value of the physical variable, and to output an intrusion signal if the result of the plausibility check is negative. Also described is a corresponding method and an alarm system including an intrusion sensor.
