A sensor system has at least one first sensor element for measuring a first physical variable and a second sensor element for measuring a second physical variable. The first sensor element is part of an application-specific integrated circuit which, in addition to the first sensor element, has further electronic circuits. The second sensor element is arranged separately and outside the application-specific integrated circuit. The second sensor element is electrically connected to the application-specific integrated circuit via a first connection point. The application-specific integrated circuit is configurable via the first connection point and the measurement signal from the second sensor element can be read out via the first connection point.

Sensor system

A sensor for detecting the mass flow rate and the temperature of a fluid flow has a mass flow rate sensor having a mass flow rate sensor element, a temperature sensor having a temperature sensor element, and an interface for power supply. The sensor converts the measured values detected in analog by the mass flow rate sensor element and the temperature sensor element into digital output signals. In order to specify the simplest and most economical sensor possible for detecting the mass flow rate and the temperature of a fluid flow, at least one analog/digital converter is arranged in the sensor, which analog/digital converter converts the analog measured values of the mass flow rate sensor element and/or the analog measured value of the temperature sensor element into digital output signals and provides the digital output signals at a single digital interface.

Sensor for detecting the mass flow rate and the temperature of a fluid flow

An air mass meter having a sensor chip. The sensor chip is constructed as a microelectromechanical system and has a sensor element, an electronic evaluation circuit and an electronic oscillator. The sensor chip is fastened to a carrier element using an adhesive. In order to specify an air mass meter which makes it possible to evaluate data in a particularly reliable and accurate manner, the sensor chip is divided into a first region and a second region. The sensor chip is fastened to the carrier element using the adhesive solely in the first region, and the sensor element and the oscillator are arranged in the second region.
