The SparkFun 9DoF Sensor Stick is an easy-to-use 9 Degrees of Freedom IMU. The Sensor Stick deftly utilizes the LSM9DS1 motion-sensing system-in-a-chip, the same IC used in the SparkFun 9DoF IMU Breakout. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer - nine degrees of freedom (9DoF) in a single IC!
The LSM9DS1 is equipped with a digital interface, but even that is flexible. The biggest difference between the two boards, besides the slimmed down 0.9"x0.4" footprint, is the number of broken-out pins, with the Sensor Stick featuring only four for quick setup and ease of use.
The onboard LSM9DS1 is one of only a handful of ICs that can measure three key properties of movement - angular velocity, acceleration and heading - in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z, and magnetic force in x/y/z.
Each sensor in the LSM9DS1 supports a wide spectrum of ranges: the accelerometer’s scale can be set to ± 2, 4, 8, or 16g, the gyroscope supports ± 245, 500, and 2000°/s, and the magnetometer has full-scale ranges of ± 4, 8, 12, or 16 gauss.
Finally, the last part I need to complete my ballistic missile.
I have one project idea using 9DOF , can we discuss ? Where should I write to ?
Hmm, install it on a vibrator so you can tell it's position, direction, and speed ?
It was in a new pair of shoes I ordered, why?
does it give rotations in quaternions or euler angles?
It gives rotation as degrees per second around each of the axes. You'd need to compute quaternions or euler angles on the microcontroller or computer.
Okay. That's the hard/expensive part. :). I was hoping this was a module that had did this on board.
Yes, but it's twice the price. I was thinking perhaps this module was a cheaper alternative, as there are already countless 9dof IMU for a fraction of the price of this this module.
How to buy this product?
A very useful toy.
It'll be perfect for my bot's inner ear!
Sleep analytics, dose anyone have a good alg for that? Thanks!
