Here's a real simple web app that displays the current temperature and humdity as reported by an SHT15.
It also provides a RESTful endpoint for simplying returning the temperature and humidity in JSON.
This won't include a guide for installing and running a Sinatra app, but here are the basics:
- Clone this repo:
git clone [email protected]:cannikin/pi_weather.git - Run bundler to install required gems:
bundle install - Start the app. You need to run it as root since the Pi requires root
access to access the GPIO ports:
sudo ruby app.rb
Now just point your browser to http://localhost:4567 and you should see the temp and humdity. The page will hit the RESTful endpoint every 5 seconds to keep the page up-to-date. That endpoint lives at http://localhost:4567/read
