Product review (1 stars): Humidity is very dry compared with reality
While the seller supplied the product promptly, and it was delivered successfully, unfortunately the quality of the product is quite poor. It is advertised as providing accurate temperatures to within a few degrees C, and that appears correct - I have other temperature sensors to compare it to. However, the humidity is supposed to be within 5 or 10%, but it is not - there were two sensors included, and both are very dry compared to other sensors that I have in the house. For example, during the recent snowstorm in NYC, while the indoor humidity from the other sensors was between 40 and 50%, these two sensors reported 5%! I could understand small deviations, but the readings are, frankly, ridiculous. If I were amazon.com I would be hesitant to offer such a product, it smirches their reputation. Sorry to have to report this.
