Abstract
A radar sensor for sensing the level of a product or the topology of the surface of a product having a continuously operated clock that closes a power supply line to the processor at a predetermined time to activate the processor. Thereupon, the processor controls the switching arrangement to activate the radar chip.
Claims15
A radar sensor for detecting a level of a product or a topology of a surface of a product, comprising:
- a permanently operated clock;
- an energy storage;
- a computing circuit;
- a radar chip;
- a first switching arrangement;
- and
- a wireless communication module,
- wherein the clock is configured to drive the first switching arrangement at a predetermined time to close a first power supply line to supply power from the energy storage to the computing circuit to activate the computing circuit,
- wherein the computing circuit is configured to drive the first switching arrangement after its activation to close a second power supply line in order to supply the radar chip with the power from the energy storage that detects the level or the topology, and
- wherein the computing circuit is further configured to drive the first switching arrangement after activation thereof to close a third power supply line to provide the wireless communication module with power from the energy storage that permits operation thereof.
A method for detecting a level of a product or a topology of a surface of a product, comprising:
- controlling a first switching arrangement at a predetermined time by a device internal clock to close a first power supply line to supply power from a device internal energy storage to a computing circuit to activate the computing circuit;
- controlling the first switching arrangement by the computing circuit to close a second power supply line to supply a radar chip with the power from the energy storage that detects the level or topology;
- and
- driving, by the computing circuit, the first switching arrangement after activation thereof to close a third power supply line to provide a wireless communication module with power from the energy storage that permits operation thereof.
A non-transitory computer readable medium having stored thereon a program element that, when executed by a computing circuit of a radar sensor causes the radar sensor to implement a method for detecting a level of a product or a topology of a surface of a product, comprising:
- controlling a first switching arrangement at a predetermined time by a device internal clock to close a first power supply line to supply power from a device internal energy storage to a computing circuit to activate the computing circuit;
- controlling the first switching arrangement by the computing circuit to close a second power supply line to supply a radar chip with the power from the energy storage that detects the level or topology;
- and
- driving, by the computing circuit, the first switching arrangement after activation thereof to close a third power supply line to provide a wireless communication module with power from the energy storage that permits operation thereof.
