| Abstract: | In order to understand measuring characteristics of capacitive humidity sensor such as accuracy, hysteresis and temperature coefficient, this paper tests three different capacitive humidity sensors. The errors of measurement value and hysteresis are compared under different temperature conditions. The results indicate that there are quite differences on temperature and hysteresis among these three sensors, which is available for the choice and use of capacitive humidity sensors. |
