Before the thunderstorm knocked them out of sync, my parents' was reading 56% while the ASOS less than 2 miles away was 46%. Analog's was reading bad but corrected itself mid-afternoon, maybe due to more wind flow as mixing got stronger. Link to comment Share on other sites More sharing options...
snowman21 Posted July 22, 2011 Share Posted July 22, 2011 They're cheap consumer grade sensors and prone to contamination causing them to read RH much higher than reality especially in high humidity situations. Not much you can really do to fix that. They're generally accurate to 3-5% under the best conditions. Accuracy tends to be worse near the oceans because of the salt in the air which provides a nice condensation nucleus. Link to comment Share on other sites More sharing options...
