1. A cuplTag logs temperature and humidity

2. The cuplTag is read by a phone.

The web address is read by a phone with NFC. This automatically opens the cuplfrontend web application in a web browser.

3. The web address is decoded.

Parts of the URL are passed to cuplbackend and in turn to the decoder part of cuplcodec. The output is a list of timestamped samples, which are stored in a database. All of this occurs automatically in under one second.

4. Samples are displayed.

Temperature and humidity data are presented to the user by the cuplfrontend web application. Samples are:

  • Retrieved by day, week or month.
  • Plotted in a graph and tabulated.
  • Exportable to CSV.
