Paul, as he describes himself, is “a student without a big budget,” which might have been part of the inspiration for this hack . Paul wanted to see how much time he was spending under the shower each day, so came up with this monitoring device using the ever-awesome Arduino processor and a RFID tag that many of you are certainly familiar with. One simply waves the tag in front of the reader to start the timer, and waves it again to stop it.
One may not, however, be familiar with “thingspeak” and “weatherspark“, two other important elements of this hack. Thingspeak is “an open application platform designed to enable meaningful connection between things and people,” and was used to interface the weather data on weatherspark with the shower monitor. This was to help figure out if there was a connection between outside temperature and the length of showers taken.
The results of this experiment should be interesting, so hopefully some will be published soon!
