The HPWREN and ROADNet teams worked on assembling a solar-powered solinst stream sensor, which measures water depth and temperature. The first test was conducted in a bucket filled with water.

The solar-powered solinst system consists of a timer, wavelan/EC-S with wireless card, a battery, and a custom-built charge controller. Although a five-watt solar panel is shown, this system is capable of powering on the datalink (twice per day) using a two-watt panel.

The solinst records the water depth and temperature - storing the the measurements internally. A ROADNet server, located at the San Diego Supercomputer Center, then listens for the wavelan/EC-S to power on and downloads the collected data, which is then made available through the ROADNet real-time data website at http://roadnet.ucsd.edu.

Additional HPWREN and ROADNet sensor equipment tests involved a 360-degree lens for an iQeye3, which is a high-resolution camera that supports wireless cards. More information on the camera is available at http://hpwren.ucsd.edu/Tech/Iqeye/.
