Real-time Weather Monitoring
Current temperature: and relative humidity:
Chose the timeline to display the results: Last 12 hours Last 24 hours Last week All time
For this visualization, we installed a DHT22 sensor on an Arduino UNO board to monitor the temperature and relative humidity and we used an Arduino Ethernet Shield to connect to the internet. The picture below shows the overall setup. Every 10 minutes, the temperature and humidity data is sent to a Google Form through PushingBox (which is a essential since Google does not accept data from unsecured devices like Arduino) and stored on this Google Spreadsheet. We then use the Google Charts to fetch and plot the data. To code the Arduino, we were insipired by this page, and to fetch and plot the data, we were inspired by Google's help page and this page.
