Abstract
In a gas sensor comprising a housing, a membrane and a sensor element, wherein the housing comprises a measuring chamber and an air supply opening, the sensor element is disposed in the measuring chamber and the membrane separates the measuring chamber from the air supply opening, a particularly good air exchange should be achieved. This is accomplished by providing a flow guiding device in the air supply opening of the housing. The flow guiding device here projects into the housing.
