Optimizing the Operating Temperature for an array of MOX Sensors on an Open Sampling System

Abstract: Chemo-resistive transduction is essential for capturing the spatio-temporal structure of chemical compounds dispersed in different environments. Due to gas dispersion mechanisms, namely diffusion, turbulence and advection, the sensors in an open sampling system, i.e. directly exposed to the environment to be monitored, are exposed to low concentrations of gases with many fluctuations making, as a consequence, the identification and monitoring of the gases even more complicated and challenging than in a controlled laboratory setting. Therefore, tuning the value of the operating temperature becomes crucial for successfully identifying and monitoring the pollutant gases, particularly in applications such as exploration of hazardous areas, air pollution monitoring, and search and rescue 1. In this study we demonstrate the benefit of optimizing the sensors operating temperature when the sensors are deployed in an open sampling system, i.e. directly exposed to the environment to be monitored.
