These data are streaming in realtime from a sensor buried in the soil of a Eucalyptus tree I'm growing on the balcony of my apartment in Berkeley, CA. I'm no green thumb so I can this tool to determine when I need to water the plant.

I use an Arduino yun to stream data from a Sensirion SHT75 sensor. I wasn't able to find a free service (Temboo etc) that would store the data and plot it in real time so I added it here. Thanks to the good folks at Google who host all this all for free on app engine.

You can read about details of the project here. The javascript plotting package above was minimally adapted from Ben Christensen's work.
