The monitor system is a solar powered data logger recording timestamp, temperature, pH, dissolved oxygen and conductivity.


Last fall I sent out a message asking what parts of the project people were interested in. I got 2 responses one asking how we picked components and one asking about solar power.

Dennis DeLorme, "Arduino at Sea".

The original plan was to update the "Solar UV Intensity" project I did three years ago on a Pacific island cruise. I presented some of the Arduino to Android interface changes last July.
But what else does an Arduino addict do when faced with an 80 day Asia/Pacific cruise? Put a bunch of extra Arduinos and I/O modules in a box and put it in his carry-on "just in case".
In addition to the UV measurement results I will talk about 2 other projects...
1) A scrolling Halloween message on an LCD display - they did some Halloween themed things on Oct 31. I used the user defined character feature to build a pumpkin image as part of the message.
2) A temperature data logger that recorded the temperatures in 6 min intervals for several hours to document problems with the A/C in our cabin. I uploaded the data from the Arduino to our laptop via Bluetooth and used LibraOffice to to graph the data.
I will talk about the hardware and software for these projects and do a couple of demos.

Dennis DeLorme, on monitoring current and voltage in his river project.

He is the director of the Prairie Waters Education and Research Center near Valley City North Dakota (http://www.vcsu.edu/prairiewaters/).
