Mystic River Open Water IOBY Campaign

Prototyping

We're currently basing our data logger prototype on the amazing open source hardware project the "mchck" -- a very inexpensive, low-power microcontroller design with on-board flash memory, a RTC.

Our fork of the mchck project is here, with datalogger functionality implemented here.

The shield we're developing for the mchck that will include hardware for measuring conductivity, temperature, and water depth is here.
