Abstract:
Sensor systems with Metal Oxide Gas (MOG) sensors with tin oxide as base material are well established as gas sensing devices for threshold applications like the monitoring of hazardous materials and dangerous situations. However, MOGs have one inherent disadvantage; they are subject to unavoidable aging processes. Therefore, the sensor systems have to be recalibrated regularly. This paper presents an innovative mathematical procedure called ReCal, which is able to determine the proper time for recalibration of the sensor system. The method of ReCal is demonstrated by simulation calculations and it is shown how to determine the parameters in real applications.
