Accelerometer and gyroscope

[MykolaLevun]

Hello,

I need to measure the tilt angles (along the x, y, z axis) of a flying device. What accelerometer can you recommend produced by STM? Will one accelerometer be enough? Or do you still need a gyroscope to complete the task?

Hi @MykolaLevun ,

 

You could look at IIS2ICLX 

On our community you can also find an article that describes how to configure the Machine Learning Core (MLC) on IIS2ICLX to implement the detection of the tilt angle, you find it here.

In addition, on Github, you can find an example on how to implement the tilt angle measurements.

Hope this helps.

For my task, a simpler chip such as LIS2DH12TR or LIS2DHTR will be sufficient. What can you say about them?

Hi @MykolaLevun ,

It depends on what accuracy you want to achieve. LIS2DH12TR is fine, you could look at the AN4509.

However, you could look at accelerometers that have better performances in terms of offset (such as LIS2DU12 or LIS2DUX12) to get an higher accuracy.
