Sensor fish

It is designed to record information such as the physical stresses that a fish experiences while navigating currents from dam turbines.

Taking 2,048 measurements each second, it is able to record five minutes of turbulence, pressure, and acceleration, saving the data to flash memory.

The following are the specifications as stated by the Pacific Northwest National Laboratory:[2] Data collected from the sensor fish is used to help create new designs for dam turbines.

Inside the turbine of that dam, the pressure changes experienced are the same as moving from sea level to the peak of Mount Everest in an instant.

The docking station sends the data to a laptop computer over USB using software developed by PNNL.
