Abstract
Extensive measurements of commercial capacitive polymeric humidity sensors were made at temperatures ranging from 73 °C to 20 °C and at a pressure of 800 Pa in order to test and validate their performance for future space missions. We found the sensor signal decreases when temperature decreases as well as a temperature independent sensor characteristic in the range from 0 %RH to 30 %RH. In addition the sensor has shown stable characteristics during thermal cycling in the range from 120 °C to 20 °C under vacuum conditions.
