Inspired by Seth, SM0AGP I bought and installed a wireless weather station that can be connected to a PC for weather analysis. The station I bought exists under different brands and this one, WP1400, is distributed by Proove International AB. It costs less than 100 USD in Sweden. The photo shows the wireless handheld indoor base station that has a touchscreen display.
This is my outdoor installation close to the 3 element yagi for the 6 m band. The outdoor sensor also has a receiver for the atomic clock transmissions from Germany.
The base station connects to the PC via an USB cable.
This is how the weather looks here today. Not so nice!
This is the main screen of the supplied software. Here you can do all set-ups. Below are screen dumps of accumulated weather data since yesterday.
