Abstract

We report an automated precision gas sensor characterization system. This system is designed for precision characterization of integrated or discrete gas sensors. Gas metering and data acquisition are computer controlled. Calibration of the gas concentration is carried out through the use of a gas analyzer or gas chromatography (GC). The system has been used to characterize two types of commercial gas sensors. The transient response of the gas sensors is therefore measured with the system reaches equilibrium first and then heating current is applied to the gas sensor to heat up the sensor from the chamber ambient temperature to the operating temperature of the gas sensor. Details of the experimental results for static and dynamic characterization of various commercial gas sensors are presented.
