Abstract

The invention relates to a sensor arrangement having a barometric pressure sensor and a thermal gas sensor, wherein the thermal gas sensor is arranged on the barometric pressure sensor or beside the barometric pressure sensor such that a gas-permeable measurement structure of the thermal gas sensor is arranged in front of a gas inlet opening of the barometric pressure sensor or in front of a pressure-sensitive surface of the barometric pressure sensor.
