Resistance Response and Heating Profiles of Electro-deposited ZnO Nanostructures for E-Nose Acetone Sensing

Abstract

This dataset contains the experimental performance records of two high-performing zinc oxide (ZnO) nanostructured sensors developed for electronic nose (E-Nose) applications. The data includes resistance measurements over time during exposure to varying concentrations of acetone, as well as the thermal characterization (heating process) of the samples. The sensors were fabricated using electrodeposition with different molarities (0.1M and 0.2M ZnCl2) and current densities (250uA and 3mA). The records show how the system responds to changes, how it recovers, and how stable the signal-to-noise ratio (SNR) is. This information is important for machine learning-based gas identification and sensitivity optimization in nanomanufacturing.
