Conclusion of the Operating Points of a Gas Sensor Set When Exposed to Domestic Gas

This study analyzes the behavior of a set of gas sensors from the French company [FIGARO/Taguchi Gas Sensors] (TGS26-series) when exposed to domestic gas under different heating voltages, with the objective of determining the optimal operating conditions. The sensors were interfaced with an Arduino board to record readings, and the collected data were processed and analyzed using MATLAB software to evaluate performance characteristics. Findings indicate that a heating voltage of VH = 5.5V yields the most favorable results, demonstrating the fastest response time and the lowest stability resistance. These outcomes highlight the optimal operating voltage for the selected sensor set. The study contributes to enhancing sensor efficiency in practical scenarios, particularly in detecting household gas leaks. This, in turn, supports efforts to improve home safety and mitigate risks associated with gas exposure. Notably, the research offers a detailed performance assessment and establishes clear parameters for optimal sensor operation, thus reinforcing both its scientific rigor and applied relevance
