Gas sensor device

A gas sensor device including a concentration sensor for measuring concentration of gas and a pressure sensor for measuring a pressure of the gas, the device comprising:

• a housing;
• a measuring chamber provided inside the housing, the measuring chamber being isolated from an air flow;
• and
• a processing circuit unit that adjusts a signal of the concentration sensor using a signal of the pressure sensor, wherein
• the concentration sensor and the pressure sensor are disposed in the measuring chamber,
• the processing circuit unit includes a response speed adjusting unit arranged to bring a response speed of a pressure signal of the pressure sensor close to a response speed of a concentration signal of the concentration sensor,
• the response speed adjusting unit has a function to remove or attenuate a high frequency signal component from a pressure signal sent from the pressure sensor, the high frequency signal component being higher than a frequency corresponding to the response speed of a concentration signal of the concentration sensor, and
• the concentration signal is corrected by a pressure signal adjusted by the response speed adjusting unit.
