Gas Detection Using a Multi-sensor Device with Pump Control and VOC Sensor - Universal Pump Sensor Control

摘要

This paper deals with the development and investigation of a volatile organic compound (VOC) system for different scenarios. The integrated multi-sensor unit can detect different gases through the integrated 3-fold VOC sensor, where-by a continuous measurement takes place. The system-integrated flow control, with pump and flow sensor, allows the gas molecules to be transported directly to the VOC sensor. The entire measurement is permanently stored on an integrated Secure Digital (SD) card. If the previously determined limit range is exceeded, an alarm is generated. Due to the combination of different components, numerous applications are possible. The system is the first step or a tool towards further developments in the field of gas sensors and is primarily used for the validation of chemically based gas sensors, and it is still largely extended by application-specific influences.
