Using the Wiimote as a sensor in water research

The $40 Wiimote (an input device belonging with the Nintendo(R) Wii(TM) game system) can be used by hydrologists as a sensor. The device contains three accelerometers and an infrared camera with built-in source tracking. It communicates by Bluetooth(R). Because of the efforts of the hacking community it is now easy to let the Wiimote communicate with a standard personal computer. Using a floating evaporation pan as an example, we show that the Wiimote, although it may have potential drawbacks when used in field campaigns, is a good addition to the hydrologist's bag of tools, especially for proof of concept testing.
