There are a few types of Weather Stations. I use DAVIS as do most of the weather stations on Wunderground.
They come with different features and add-ons, like one to measure ground temp for planting.
They send a wireless signal to a console at your home. It is a strong signal (a relay is also available), much better than WiFi. The console collects and displays data on the console screen.

The console can also be connected to the internet through your computer and will upload to your website as often as you tell it too, I use every 2 minutes. I started in DEC 2009 (Christmas present from Rosey).
You don't need a website, you can register your site at Wunderground and upload there. Your computer and the Wunderground site will keep a searchable archive of your data.

The thing is solar powered and works near perfect. If you scroll to the bottom of a Wundegrground station page, you can see stations nearby and the data should fall in a similar range if the station is accurate and installed properly.

Since my station is on an open lake with a flat view for a mile, it differs more especially as to wind speed. Also being in the foothills, elevation change is rapid to some nearby stations.

Toad is here and the differences will be less.

I you want to go on line you need the DAVIS weatherlink and the computer software. You don't have to go online as the console has all you need.

DAVIS is not part of Wunderground and also has an online service if you don't want to use Wunderground, and there are others.
Wunderground is versatile, and I recommend it. It is free or the upgrade is just $10 a year.

Some of us have our own website, here is mine:

Most don't have a separate website, but some are very elaborate with webcams and advertising as for a town, lodge, etc. Most anything can be done there.

Anyone who gets into this hobby just contact me. It can be tricky at first, but can be done by us all.
