This neat water temp sensor tied in with my existing Wittboy Pro weather console. For the 1st time ever in my lifelong aquatics hobby I can ensure via modern tech that the fish tank's temp is as it should be. Also really good for reviewing fluctuations overnight via the app graph when the room is colder. My third time using weather spares for bolt ons for the Ecowitt system but as always great service, good advice and rapid delivery. Thanks again
I have two stations, a Davis and an Ecowitt. The Ecowitt is more for fun, but it still provides some good data for other aspects of measurements.
I bought this so that I could monitor my Koi pond temperature. I have the data feeding to my website in real-time, so I can monitor it at any time and any location.
It may seem a novelty, but I find it very handy!
I like the way it is put together, too. It screws in to a mounting bracket, so as long as the bracket is secure, the sensor won't go anywhere. Very happy!
