### IOBY Campaign

Public Lab is partnering with IOBY to develop a low-cost water quality monitoring network for the Mystic River.  Here's the crowd-funding campaign, which ends February 14th:

### Prototyping

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

Our fork of the mchck project is [here](https://github.com/bgamari/mchck), with datalogger functionality implemented [here](https://github.com/bgamari/data-logger).

The shield we're developing for the mchck that will include hardware for measuring conductivity, temperature, and water depth is [here](https://github.com/bgamari/water-quality).
