Editing Alcohol Sensor Based on Gas-Sensitive Resistive Materials (section)

== Limitations and Future Improvements ==

The current system demonstrates alcohol detection and basic response behavior, but its performance is limited by the lack of calibration, uncontrolled measurement conditions, and restricted data resolution. The sensor output is expressed as a scaled ADC value rather than a calibrated ethanol concentration, which prevents quantitative interpretation of the results. In addition, the use of a simple closed chamber leads to diffusion-dominated and non-uniform vapor distribution, reducing repeatability across measurements. The data acquisition system, including limited ADC resolution and simplified processing, further constrains the precision of dynamic analysis. Future improvements should focus on introducing calibration, improving environmental control, and enhancing data acquisition and analysis methods to achieve more reliable and interpretable measurements.
