U researchers implement wireless water sensors
At Pamela Park in Edina, Chris Wennen , a graduate student in water resources science at the University of Minnesota, stands knee-deep in a pond, examining what resembles an enormous film canister.
The device is a wireless sensor that monitors water quality. It is one of five implemented in the Minnehaha Creek area.
Wennen said the sensors measure the levels of pollutants such as nitrate and chloride, as well as the amount of oxygen, pH, temperature, turbidity and depth of the water.
