The Salamander stream-sensor project is archived here. You can find circuit board design files for building water sensors based on the Moteiv/Crossbow/MEMSIC Telosb/TmoteSKY low-power wireless sensor network. From about 2007-2012 we developed 1-wire sensor capability (hardware and software) and housings so that users could add a string of underwater sensors to a single radio. We carry on developing compatible low-power flex, impedance, and chemical sensors in the Harnett lab at the University of Louisville, and studying sediment transport at the Fox lab at the University of Kentucky.
