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.
Claims11
An energy-autonomous sensor for detection of physical environmental parameters, comprising:
- one sensor element for detection of physical environmental parameters;
- a control circuit for encoding of the detected physical environmental parameters;
- a radio-frequency transmitter for transmitting the encoded detected physical environmental
- parameters together with an ID number of the sensor;
- a storage element for storage of electrical energy;
- an electrical power generator adapted to convert energy in the surrounding area into electrical energy and wherein the electrical power generator is coupled to the storage element in order to supply power to the sensor;
- and
- a timer circuit which is activated upon a predetermined electrical voltage on the storage element being reached, activates the sensor element and the control circuit at a predetermined time interval, and deactivates them after a predetermined operating time, such that this results in a time duration of sensor operation and time duration of sensor operation pause.
