Thanks for your reply, we are not hobbyists' and this is not a hobby project for us, we are serious in designing the sensor that will work better than your suggested Sensirion part from Digikey. We have designed the sensors and the probe to read the capacitive sensor with success and we are...
Thanks for your reply. if Cellophane will at 100% Rh, swell and may not come back to its original position, or the reaction time will be very slow, it will not work in my application. , so what do you suggest? Do you have any other suggestions?
I am working on a capacitive humidity sensor, using polymer as a dielectric between two electrodes, does anybody know which polymer would react best to water vapor or water moisture or Rh (Relative Humidity)?
