The new USB-powered JoyWarrior24F14 sets a new price/performance benchmark for USB-based acceleration sensors, and offers acceleration resolution down to 125ìg.
JoyWarrior24F14 modules are based on a MEMS sensor and measure with 14-bit resolution in the ranges ±1g, ±1.5g, ±2g, ±3g, ±4g, ±8g, or ±16g, delivering 125 results per second.
Connection via USB allows easy use with almost any computer. Since JoyWarrior24F14 ennumerates and works as a joystick, accessing the data can be easily done via the operating system’s joystick API without installing any specific drivers. Of course, this means that you can use JoyWarrior24F14 in joystick applications too.
Software provided free operates on Windows and MacOS X platforms and contains a configuration tool to set the sensor parameters, with tilt angle measuring, a calibration tool, and a simple data recorder. Small size (30 x 33 x 5mm) and a low mass (<5g) allow installation of the sensor in many situations. The modules are suitable for acceleration, tilt, and low frequency vibration sensing, as well as for human input applications. An additional 8 digital inputs are available for buttons or other logic signals.
Made in Europe by peripheral IC experts Code Mercenaries, JoyWarrior24F14 is the standard sensor used in the Quake Catcher Network of the University of California. The project allows computer users to participate in a network that measures seismic events.
