I have had this sensor for well over a month but only recently started paying attention to the humidity readings. They seemed extremely low so I decided I would compare it to several of my highly accurate (Caliber IV) gauges. I placed the sensor along with 2 other gauges inside a ziplock bag noted the differences. In just over 1 hour, there was a difference of 12 % (low) between the Multi-sensor and my other gauges. I will keep the bag sealed for another 24 hours to ensure all gauges are “climatized” to this environment but I am very doubtful I will be happy with the results.
Has anyone tested other humidity sensors and found one or more with greater accuracy???
BTW: The (5) gauges used in this test are calibrated each year at 32%, 43% and 75%. Each is accurate with +/- 1%
