Abstract

The invention relates to a sensor device for monitoring accelerations to which an object is subjected. In order to detect whether a value has exceeded or is below a threshold for the acceleration to which objects have been subjected in the past, i.e. without having visual contact with the sensor, the inventive sensor device includes an acceleration sensor, which is permanently linked to the object to be monitored, so that a relative movement between the acceleration sensor and the object is prevented, and an RFID transceiver for non-contact coupling of electrical energy into the acceleration sensor and for sending out radio signals as a function of the physical state of the acceleration sensor.
