Product Description

The Dual-Axis Gyro module carries the IDG-500 from InvenSense. The IDG-500 uses complex, high-performance MEMS technology to offer 500°/sec full scale range and 2mV/°/sec sensitivity of rotation, and also includes a patented “Auto Zero” feature for minimizing bias drift over temperature. Because temperature sensing is required for its function, the IDG-500 is also able to read out temperatures from -20 to 85 C too. The really great part is how easy the sensor is to use because of its analog output. Just run the Xout or Yout outputs into an A/D converter. For more gain, use the 4.5x outputs that amplify the signal 4.5 times. Even though the IDG-500 chip is designed for a 3V power supply, the board itself has a voltage regulator so it can be used with any voltage from 3-6 volts, making it ideal for Arduino-based projects. The Dual Axis Gyro module’s 3V regulator can also be used as a 3 volt reference, for example to hook up to an Arduinos AREF input, which will scale the values that the microcontroller will output to a 3 volt input, for more precision in the A/D converter. The sensor ships assembled and tested, but with the pin headers loose, to allow users to mount the sensor in any manner they choose.

Hook it up

Hook up ground (Gnd), Vin (with 3-6 volts), and hookup the signal voltages at Xo, Yo or  Xo4, Yo4 to your AtoD converter (analog pins). The output voltages on the Xo4 and Yo4 are the same as the Xo & Yo voltages, only 4.5 times larger (good for slowly rotating objects). The jitter is larger too, as you might imagine.

Ideas

Combine a Dual Axis Gyro with a JeeNode and/or accelerometer you have a nice portable data sensor for human (or robot) bodies. Gyroscopes are the uber tools for creating balancing robots. Smart young twenty-somethings at MIT are also hard at work trying to figure out how to insert these into us geriatric types, so we won’t be so hard to take care of when we’re senile. The Dual Axis Gyro Module comes fully assembled and tested, but with the 6-pin male headers provided unmounted.
