Adafruit launches a new 9 Degree of Freedom sensor

The Open source hardware giant Adafruit released a new Precision 9 Degree of Freedom (9-DoF) sensor for a price tag of $14.95. The little sensor has been intended to give top notch motion direction and orientation sensing and is the ideal expansion to your next Arduino project. The little breakout board contains two chips that sit one next to the other to give 9 degrees of full-motion data.

Adafruit explained-

“The board includes an LSM6DSOX, a 6-DoF IMU accelerometer + gyro. The 3-axis accelerometer can tell you which direction is down towards the Earth (by measuring gravity) or how fast the board is accelerating in 3D space. The 3-axis gyroscope can measure spin and twist. This new sensor from ST has very low gyro zero rate and noise, compared to the MPU6050 or even LSM6DS33 so it’s excellent for orientation fusion usage: you’ll get less drift and faster responses.

The LSM6DSOX has flexible data rates and ranges. For the accelerometer: ±2/±4/±8/±16 g at 1.6 Hz to 6.7KHz update rate. For the gyroscope: ±125/±250/±500/±1000/±2000 dps at 12.5 Hz to 6.7 KHz. There’s also some nice extras, such as built in tap detection, activity detection, pedometer/step counter and a programmable finite state machine / machine learning core that can perform some basic gesture recognition.”

The Adafruit 9 Degree of Freedom sensor additionally incorporates a LIS3MDL 3-axis magnetometer that can detect where the most grounded magnetic power is originating from, for the most part used to distinguish magnetic north. The three triple-axis sensors indicate 9 degrees of freedom, by joining this information you can orient the board.
