3DM® is a 3-axis orientation sensor capable of measuring: +/-180˚ of yaw heading, +/-180˚ of pitch, and +/-70˚ of roll. Orthogonal arrays of magnetometers and accelerometers are used to compute the pitch, roll and yaw (also refered to as heading or azimuth) over a wide angular range.

The 3DM® is sold as a starter kit for the first unit purchased, after which, just the board can be purchased. The starter kit includes the standard board, enclosure (shown), software, requisite serial communications and power cable, and a manual.

The Windows® software provided communicates with 3DM® over a serial port. The software gives the user complete control over how data is processed, presented, and logged. The output may be programmed to provide raw magnetic field and accelerometer outputs, or processed pitch, roll, and yaw outputs. User programmed digital filters are used to process sensor data either statically or dynamically, depending on the change in 3DM® movement over time.

3DM® runs off of a single supply positive voltage ranging from 5.2 to 12 volts DC. 3DM's can be used alone or combined in networked arrays.
