摘要： A digital sensor has a sensor element, a digital section, a sample-and-hold stage and an output stage, and storage storing electrical energy, each of which are supplied with electrical energy by a power supply. In the event of a failure of the power supply, the sample-and-hold stage and the output stage are provided with power by the storage storing electrical energy, such that the measurement value most recently stored in the sample-and-hold stage is provided in the signal line by the output stage until the failure of the power source has ended and a new measurement value is stored in the sample-and-hold stage. No electric power is supplied to the sensor element by the storage storing electrical energy in the event of a failure of the power supply.

摘要： A method for operating an air mass sensor arranged in the intake section of an internal combustion engine and configured to measure the mass of the air flowing through the intake section includes the air mass sensor detecting a stationary state of the internal combustion engine using an element for evaluating measurement signals generated by an air mass sensor element, and, in response to detection of a stationary state, switching the air mass sensor element into a second operating mode that reduces contamination of the air mass sensor element. The second operating mode permits at least one measurement of the air mass flowing in the intake section, as a result of which the air mass sensor itself detects a starting of the internal combustion engine using the element for evaluating the measurement signals generated by the air mass sensor element.
