Questions tagged [accelerometer]

An accelerometer is a device that measures the proper acceleration of the device.

From Wikipedia:

An accelerometer is a device that measures proper acceleration. The proper acceleration measured by an accelerometer is not necessarily the coordinate acceleration (rate of change of velocity). Instead, the accelerometer sees the acceleration associated with the phenomenon of weight experienced by any test mass at rest in the frame of reference of the accelerometer device.

For example, an accelerometer at rest on the surface of the earth will measure an acceleration of g=9.81 m/s^2 straight upwards, due to its weight. By contrast, accelerometers in free fall or at rest in outer space will measure zero. Another term for the type of acceleration that accelerometers can measure is g-force acceleration.

Most questions regarding this tag deal with how to access, interpret, and process accelerometer data that is abundant in smartphones.

georeferencing a trajectory from inertial sensors (IMU)

There are data from tracking a moving object based on inertial measurement unit (IMU), using sensors like accelerometer, gyroscope, magnetometer. From these data (by sensor fusion) is generated a trajectory (polyline) and rendered into…

Best approach for detecting periods of vibration with an accelerometer

I'm working on a camera scanning application, and I've noticed that there is a degree of vibration after movement (some axes are worse than others). I've attached an I2C accelerometer/gyroscope (MPU 6050) as close to the image sensor as I can get,…

Google Pixel 6 Pro Gyroscope and Accelerometer issue

The Gyroscope and Accelerometer sensors are defective. As a result, features that require these sensors do not work such as Auto-rotate, Compass, Flip to shh, Flip camera for selfie and games that require these functions. The sensors work again…

Keep the identifier for each row in a rolling window of functions R

I have managed to apply a rolling window of functions per column of my accelerometer data where each row is associated with a behaviour. However, the output doesn't include the behaviour associated. Is there a way to either keep the behaviour per…

Accelerometer Uncalibrated gives different values when also registering to Gyro Uncalibrated

I found out the weirdest thing. I'm dumping SensorEvent.values[2] to the console and when I'm just registered to the Uncalibrated Accelerometer this hovers / averages around 9.84 (slightly off on this phone). But when I also register to the…
