Abstract
An energy-autonomous sensor for detection of physical environmental parameters, having at least one sensor element, one storage element and one control circuit, with a timer circuit which is activated on reaching a predetermined electrical voltage on the storage element, activates the sensor and the control circuit at predetermined time intervals, and deactivates them after a predetermined operating time, such that this results in a time duration of sensor operation and a sensor operation pause.
