Response Time

Definition

Response time refers to the duration it takes for a biosensor or environmental monitoring device to detect a change in the environment and produce a measurable response. This term is crucial in evaluating the efficiency and effectiveness of these devices, as shorter response times generally indicate better performance in detecting pollutants or changes in environmental conditions.
