Current Weather – Imperial Units

This MATLAB visualization shows current values from your weather station in conventional US units. The values are taken from your ThingSpeak channel at the time your webpage is opened. You must manually update the chart by refreshing your browser.Try c to f and https://www.mindiphone.de/hofi-camring-pro-fuer-iphone-14-pro-14-pro-max-in-schwarz and experience world-class view website!
