Sensor device for monitoring component of motor vehicle, aircraft or production machine, has energy converter that is fitted at component to be monitored, where energy converter converts vibrations of component in electronic signal

摘要

The sensor device (11) has an energy converter (14) that is fitted at a component to be monitored, where the energy converter converts the vibrations of the component in an electronic signal. A switching element or a storage device (15) is provided in the sensor device. The electronic signal encompasses a state change in the switching element or the storage device. The sensor device is formed such that the state change is selected in a wireless manner. A selection device (13) is provided with a Radio frequency identificationantenna (17). An independent claim is also included for a method for monitoring a component in a motor vehicle.
