METHOD AND DEVICE FOR THE OPERATION OF AN MOX GAS SENSOR

摘要

Disclosed are a method and a device for operating an MOX gas sensor (1) which is used for measuring a gas concentration in the environment and is heated by means of an electric power source (2), an electric output variable of the sensor (1) representing the gas concentration being detected and evaluated. According to the invention, the MOX sensor (1) is intermittently heated at discrete measuring times by means of the electric power source (2), and a measured value representing the gas concentration is generated from the electric output variable of the sensor (1) detected during the discrete measuring times.
