For adequate measurement of air humidity in plant environment, characteristics of humidity sensors of ventilated psychrometer of resistance thermometers (Ps), lithium chloride relative humidity sensor (Lr), electric capacitance meter with filter (Ec), electric capacitance meter without filter (Ec-n) and absolute humidity sensor of thermistors (Ab) were examined. Static characteristics indicated that all sensors used can be applied to humidity measurement with sufficient accuracies in steady state. In dynamic characteristics, appreciable differences were found among these sensors; Ec-n was more sensitive to both absolute humidity dynamics and air temperature dynamics as compared with Ps, Lr, Ec and Ab. In particular, Lr and Ec were not able to follow to air temperature dynamics. Thus, Ec-n was estimated to be reliable for exact analysis of humidity dynamics under rapid change in air temperature, such as the vapor flux analysis, and for accurate control of air humidity.
