Questions tagged [accelerometer]

Accelerometer is a sensor that measures acceleration.

Accelerometers may measure acceleration on one two or three axis. It is useful in deduced reckoned navigation of robots. All accelerometers measure 1G og force due to the gravitation of the earth.

Coordinate transform of accelerometer on rigid body

I have a question about something that seems like it would be pretty basic, but so fair I haven't been able to find a whole lot of discussion on the issue. It's possible I'm not not familiar enough with the terminology. I have a rigid body with an…

How to interpret and use values of an accelerometer

Currently, I'm building a quadcopter using Arduino. To make the copter able to stabilize I use an mpu6050 accelerometer + gyroscope. I understand that I can get the angle of rotation by integrating the values of the gyro. I understand too that I can…

Accelerometers error (BMA020 and BMA180)

Recently I am working with two accelerometers: BMA020 and BMA180. I will try to explain my problem using BMA020 as example because it is less accurate therefore problem is more visible. When I hold my Acc in neutral position I get correct average…

Accelerometer deterministic errors

I am working on MEMS accelerometers, and I want to understand the difference between, Cross axis sensitivity Axis Misalignment Non Orthogonality In literature, people use it interchangeably. These physical parameters cause deterministic errors,…

Are there any analog data loggers for recording PCB 353b33 accelerometer datapoints for a minute or more?

I'm currently recording data points from an analog accelerometer(PCB 353b33) using a TDS3014B oscilloscope which has a Record Length of 10,000 points at a Sample Rate of 1.25 GSa/s. Since the oscilloscope is a triggered data logging device, it's not…

Using an accelerometer for position

I have some accelerometers hanging from strings. I would like to be able to compute the position of the string from the accelerometer reading. What I think I need to do is: Compute a transform from the accelerometer at rest in order to normalize…

MPU-6050 as a compass not affected by magnet!

I am using an MPU-6050 as a compass connected to an Arduino Uno and using the AccZ register presumably from the accelerometer. So, first question, is the magnetometer signal processed internally with the magnetometer output to give true angle in…
