Sensitivity: sensitivity to gases
Response time: response speed to the measured gas concentration
Selectivity: refers to the ability of a gas sensor to distinguish the gas species under the condition of coexistence of multiple gases: when the measured gas concentration is constant, if other conditions change, the gas sensor output characteristics remain within a specified time. Constant ability temperature characteristics: characteristics of gas sensor sensitivity as a function of temperature. Humidity characteristics: characteristics of gas sensor sensitivity as a function of environmental humidity. Power supply voltage characteristics: characteristics of gas sensor sensitivity as a function of supply voltage Timeliness and interchangeability: The time to reflect the stability of the gas-sensitive characteristics of the component is the timeliness; the consistency of the gas-sensitive characteristics between the components of the same model reflects its interchangeability.
