Abstract
A semiconductor gas sensor, for example for measuring CO, NOx, O3, etc., exhibits a heatable sensor element for measuring gas concentrations, and a housing in whose interior the sensor element is disposed. The housing has a first opening, which connects the interior to the exterior. The housing has one or more second openings, which lie deeper than the first opening so that a gas stream is driven by means of convection from the second opening to the first opening. The semiconductor gas sensor can be made of silicon by means of micro engineering.
