Thank you. I haven't actually got my accelerometer yet. I have an experience with an HMR magnetometer being too noisy. I thought maybe accelerometer was similar. But just in case the noise was large, what would you suggest I do?Acceleration data should not be noisy. What problems are you having or are you just antipating?
Most accelerometer chips allow you to specify a low pass digital filter when you configure it. There are many options. Most default at a cutoff frequency about 1/4 the sampling frequency you select.
If you are getting noise from a stationary circuit, then you have an electrical issue in your circuit.
Thank you for sharing. But what would you suggest for smoothing, a kalman filter or high-pass - low-pass filtersIs this accelerometer data considered noisy? Sure looks noisy compared to the real profile from simulation. If you want to do anything useful with the measured data (integrate, get thrust or drag profiles, then some filtering or smoothing is needed.

I don't know much about filters. I may simply fit a least-squares curve through the data of interest. For example, I want to compute drag coefficient, so only the coast phase of the flight is needed. In my example above, from t = 2 s to 16 s, a logarithmic fit may work.Thank you for sharing. But what would you suggest for smoothing, a kalman filter or high-pass - low-pass filters
