The Open Water Project
The Open Water Project aims to
- develop and curate open hardware and open software useful for water-related applications
- build and facilitate data infrastructures that allow for easier sharing of water data
- encourage the growth of communities focused on 'free and open' approaches to water science
- support ongoing work by grassroots communities interested in their own local water quality issues
To this end, we've been focusing on several initiatives, in particular:
The RIFFLE: An Open Source Datalogger. We are working to develop an open source hardware datalogger that can be placed in the field for extended deployments and measure common water parameters like temperature, conductivity, depth, and turbidity. The main Public lab wiki for this device is here. For recent research and descriptions of projects, you can search for 'riffle' on Public Lab, via this link.
The Coqui: using audio as a sensor data format. We're also exploring using audio frequencies to convey sensor readings -- like a modem, but even simpler -- in order to make sensor readings more accessible for people (or to enable data transmission over ubiquitous audio jacks on PCs and smartphones). Read more about this idea on the Coqui wiki, or look for recent updates on Public Lab here.
A mailing list. Sign up for the plots-water-quality email list, and participate in discussions about low-cost, open source water quality monitoring tools and techniques.
We'd also like to use this wiki as a place to post links to other projects that embody an 'open science / open source' approach to hydrology and water technologies. Please add your links below!
