This page is a description of Public Lab's efforts to develop low-cost open hardware tools for assessing water quality on the Mystic River.
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:
Mystic River Open Water IOBY Campaign
Water Quality Monitor Prototypes
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.
