Response time of the sensor to change of humidity: air, RH70 ⇒ air, RH80; Sensor signal is calculated as (R0 − R)/R0, where R0 is the sensing layer resistance in dry air and R is resistance in air with current humidity. Response time to changing humidity is ~10 s (τ90—time necessary to reach 90% of final value of conductivity).
