### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very accurate, simple integration
  

*by D***E on Reviewed in the United States on February 13, 2020*

Great sensor.Please mind the model numbers on these sensors, they look identical.WH31B is your main indoor sensor.WH31 is a completely different beast.Depending on your weather station you can have up to (8) WH31's.But there can be only (1) WH31B on any system I know of.I thought I could have (2) of the WH31B's, I was wrong. This was confirmed by Ambient's OUTSTANDING tech support. The additional sensor now in drawer, powered down, as a backup.I have 3 of the WH31's connected to my weather station.They all work great.

    Simple.
  

*by T***R on Reviewed in the United States on May 13, 2019*

Simple installation. Uses only 2 screws. Easy setup. Simple flip of a dip switch to designate the remote number and insert 2 AA batteries. The console connects very quickly with the sensor close by. Since this connects to the WS2000 I can place it anywhere I want and I can read it from my WS2000 console or my smart phone.I bought 2. One for the backyard and one for the garage. A quick glance at the console and I know the temp and humidity all around my house.

    Great addition to an Ambient Weather Station
  

*by T***N on Reviewed in the United States on November 8, 2019*

I bought an Ambient weather station last Christmas and needed some extra sensor around the house so I got these.  They work quite well and I have not had any issues getting them linked up with the base station or with them losing signal.  They are slightly larger than I would prefer but they arent too big that they are a problem either.
