Weathervane is a simple Sinatra app that takes the parameters of a GET request and displays them on a webpage.

It is one part of a larger STEM lesson plan around composting and computer science.

See also the [companion compost monitor sketch] (https://github.com/jsimms/compost_monitor), and 5 minute composting lesson.

Big thank you to Open Home Automation for putting up [a PHP version of this app] (https://github.com/openhomeautomation/wifi-weather-station). I simply rewrote it using Ruby and Sinatra.

Please feel free to improve Weathervane, or any other part of the lesson plan.

Here are a few things I'd like to eventually add to Weathervane.

• Be able to identify unique devices
• Store data into a database instead of creating txt files
• Create visual charts to show temperature and humidity over time
• Send email or SMS alerts when a pile is cold

But there are tons of other things as well.
