Data Logging the IBC digestors

Data Logging is a crucial part of our work, but achieving the capability to do it reliably and cheaply isn't so easy.

Before I left for Florida I set up an Arduino with RTC (real time clock) powered by a solar panel for the internal digester in our Mercy College shed.  It started on May 18 and apparently lost power after 5 days on May 23. I just powered it up today, June 4, and got one reading.
