If you're passionate about weather and regard it as either your avocation or even your occupation, then you probably don't need to be told what Wunderground.com is. It's the website for the Weather Underground. No, not the one-time radical left-wing group responsible for bombings and demonstrations in the 1970s, but the commercial weather service that was formerly part of the Weather Channel and continues to make local weather data available for free over the Internet to anyone who either needs to know or wants to know what's happening or about to happen in the atmosphere.
Weather Underground gets its meteorological information from a large number of sources, including the National Weather Service, but much of their data, especially the hyper-local part of it, comes from personal weather stations owned by ordinary weather enthusiasts. People, quite possibly, like the ones reading this website.
The Ambient Weather WS-1001-WIFI is such a weather station. It monitors outdoor temperature, humidity, wind speed, wind direction, rainfall, UV and solar radiation and automatically transmits that information to wunderground.com, where it becomes part of the vast database of hyper-local weather available to anyone who checks in with the site. The WS-1001-WIFI, like other weather stations that will connect to Weather Underground, goes beyond just letting you monitor the weather in your immediate neighborhood (or farmyard or wherever else you need hyper-local weather) and lets you become part of a network of weather enthusiasts who are eager to share their local information with the world.
The WS-1001-WIFI is a tremendously sophisticated weather package, but PC Magazine complains that it's difficult to set up and far from ideal for casual weather watchers. If you want to shop around for alternatives, see the Netatmo NWS01-US and the Ambient Weather WS-1200.
Worked as described for about three months and totally failed. This unit is too inconsistent and unreliable to be put in a remote location.
The Ambient Weather Observer is clearly made with the hobbyist in mind, and as a result packs incredible capability into a durable, if inelegant, package.
I'm very happy with this station. The setup was easy, including connecting with Wunderground. I like that I can see the data on the internet. I feel I got a lot better deal.
