## 2. PROJECT CONTEXT
This dataset contains experimental sensing data for Zinc Oxide (ZnO) nanostructured sensors developed for Electronic Nose (E-Nose) applications. The samples were fabricated via electrochemical deposition using Zinc Chloride (ZnCl2) electrolytes.

## 3. FILE OVERVIEW
The dataset consists of four (4) CSV files representing two key samples (0.1M and 0.2M ZnCl2):

- 0.1MZnCl2-250uA-60s.csv: Main sensing experiment (resistance vs. acetone concentration) for the 0.1M sample.
- 0.1MZnCl2-250uA-60s-Heating.csv: Thermal characterization and baseline stabilization for the 0.1M sample.
- 0.2MZnCl2-3mA-10s.csv: Main sensing experiment for the 0.2M sample.
- 0.2MZnCl2-3mA-10s-Heating.csv: Thermal characterization and baseline stabilization for the 0.2M sample.

## 4. DATA STRUCTURE & UNITS
All files are in comma-separated value (.csv) format. 

### Columns in Sensing Files (*.csv):
- Loop: Measurement cycle iteration.
- Time(s): Elapsed time in seconds.
- Resistance(ohm): Sensor electrical resistance measured in Ohms.
- O2 (L/min): Flow rate of Oxygen.
- N2 (L/min): Flow rate of Nitrogen (carrier gas).
- 10ppm Acetone in N2(ml/min): Flow rate of the target gas mixture.
- Acetone concentration(ppm): Final calculated concentration of acetone in the chamber (0.1 to 1 ppm).

### Columns in Heating Files (*-Heating.csv):
- Time(s): Elapsed time during the heating phase.
- Resistance(ohm): Sensor resistance during thermal ramp/stabilization.
- Temperature (C): Operating temperature in degrees Celsius.

## 5. METHODOLOGICAL INFORMATION
- Equipment: Data acquired via a Keithley 2700 digital multimeter.
- Target Gas: Acetone (0.1 ppm - 1 ppm range).
- Operating Temperature: 300°C (stabilized).
- Synthesis: Electrochemical deposition (Chronoamperometry/Chronopotentiometry) followed by calcination at 400°C for 2 hours.
