Sensor fish

A sensor fish is a small, plastic tubular device containing sensors. It is designed to record information such as the physical stresses that a fish experiences while navigating currents from dam turbines.〔(【引用サイトリンク】title=Sensor Fish show how hydroelectric dams will affect salmon )
==Description==
thumbnail
Created by the US Department of Energy's Pacific Northwest National Laboratory (PNNL), the tubular device is 9 cm (3.5 inches) long, 2.5 cm (1 inch) in diameter, and weighs 42 grams (1.5 ounces). It is roughly the same size as a juvenile salmon. The sensor fish has neutral buoyancy allowing it to remain underwater. Inside are sensors and a lithium-ion battery. Taking 2,048 measurements each second, it is able to record five minutes of turbulence, pressure, and acceleration, saving the data to a flash memory. It records a maximum of 1.2 MPa (174 pounds per square inch) of external pressure, up to 200 gs of acceleration, temperatures ranging from -40 to 127° C (-40 and +260 degrees F), and rotational velocity of up to 2,000 degrees per second.
