Summary:PROBLEM TO BE SOLVED: To measure gas concentration in a closed container or the container of a constant volume. SOLUTION: A gas concentration sensor 10 includes a pressure sensitive device 12 arranged inside a container. The pressure sensitive device 12 generates a first electric signal having a functional relation to a gas pressure inside the container. The gas concentration sensor 10 includes an electronic circuit connected to the pressure sensitive device 12, amplifying the first electric signal and generating a second electric signal having a functional relation to a gas concentration in a volume at an optional temperature.
