A sensor device includes at least one sensor, a digital signal processor and an amplifier. The at least one sensor is configured to measure a variable physical quantity and provide a raw sensor signal at an output of the at least one sensor. The digital signal processor is configured to preprocess the raw sensor signal output by the at least one sensor into a sensor signal and to further process the sensor signal into a pulse-width-modulated output signal having a duty cycle that is dependent on the measured quantity using a plurality of device-specific correction parameters stored in a memory to convert the sensor signal into the pulse-width modulated output signal. The amplifier is configured to convert the pulse-width modulated output signal into an analog voltage or current signal.

Sensor device and method for operating a sensor device

A sensor device includes a system carrier including at least a first planar support element and a second planar support element. The support elements are disposed in a mounting plane at a distance from one another. An integrated signal-processing component is disposed on the support elements. An encapsulation at least partially encloses the signal-processing component. At least two temperature sensors are integrated within the signal-processing component. Each of the temperature sensors is disposed in a vicinity of a respective one of the support elements.

Sensor device having integrated temperature sensors

A circuit arrangement for capacitive humidity measurement that includes a capacitive element to be measured, a plurality of switch elements, a charge storage element and a control unit electrically connected to the capacitive element, the plurality of switch elements and the charge storage element. The control unit controls the plurality of switch elements so that a number of charging operations and a number of discharging operations of the capacitive element are performed, as well as a parallel charging of the charge storage element takes place, until the charge storage element has been charged to a defined reference value, and a determination of a capacitance of the capacitive element is performed from a determination of the number of charging operations, or of a time until the reference value is reached.
