Hi Jet, Thank you for talking with your experts. I would definitely use a precise humidity barometer but I actually do not need an accurate value of absolute humidity. I am only focusing on the change in humidity. The actual value is not important for my applications, I just need to know if the humidity is changing. I want to use the sensors to detect water leaks into a container. I am using the jar right now as a control because I know no water can get in or out, but I am not getting constant humidity from the sensors. This is not a big problem if I could predict the innaccuracy of the sensors. I want to understand why they are not giving me constant humidity so I can take it into account in my data analysis so I can understand what an enivronement without constant humidity would look like with these sensors. Right now, I know that an environment with constant humidity gives me data without constant humidity. If I can understand this fluctuation in humidity in the sensors, I can better understand what it would look like if the environment stopped having constant humidity. You mentioned the sensors have a deviation with the real ambience and I agree that it is acceptable since I do not need an accurate sarting value for humidity. I only care about if that value increases or not. If the only error in the sensors was a deviation in value, than I would not expect the problem I am having and I am unsre if calibration would fix this beacause the humidity read by the sensors would probably still fluctuate. Even if the sensors did not give me an accuarate value of humidity, I would still expect that humidity value to be constant but I am not seeing that. The relationship between the RH and temperature from the sensors is not consistent with constant humidity. I expect the temperature and relative humidity to change but I expect them to always correlate with the same absolute humidity. I made this graph last year and you can see that at a constnt AH, the temperature and relative humidty values can change but still correlate to that AH value. Therefore, I expected to see a constant humidty in the jar based on the RH and temperature values given to me by the sensors. Thank you for your consistent responses. Please let me know if you think I am wrong in anything or if you need any more clarification. I am open to being wrong, but I would like to know where and why I am wrong so I can better understand.
