Im' getting another sensor for mine so I can measure from both my tanks at the same time on the one station. you can use up to 3 sensors with one base from what I've read. it seems more accurate then my old none digital one, right now its reading 81.3F, and 87 percent humidity, so I'm turning down his humidity just a tad to get to 85 Also, it says on the back it runs at 433.9MHz so it wont interrupt any network I've heard of
