Ozone-Differentiated Gas Sensor Performance Data for Indoor Pollutants

Experimental data from synthesized transition metal oxide-modified SnO2 gas sensors for monitoring indoor air pollutants. The dataset likely contains measurements of sensitivity and selectivity toward p-xylene and formaldehyde, modulated by ozone, with performance metrics like response values and detection limits. Linghao Wu authored the dataset, which was last updated on 2026-05-19.

Use Cases

• Calibrating sensor arrays for p-xylene detection based on described response enhancement from ozone modulation.
• Comparing sensor performance for formaldehyde detection based on described opposite performance effect.
• Evaluating the impact of ozone on electron depletion layer thickness and conductivity signal amplification.
• Training models to predict sensor response based on operating temperature and analyte concentration.
• Optimizing material synthesis strategies for gas sensors based on the described coprecipitation method and surface active site enrichment.

Strengths

• Includes specific performance metrics, such as a response value of 16.73 to 5 ppm p-xylene at 260 °C with ozone.
• Reports a calculated limit of detection (LOD) of 35.98 ppb for p-xylene.
• Describes a nearly 5-fold performance enhancement versus pristine SnO2 due to TMO modification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect experimental bias inherent to the specific laboratory setup described.
