Hi! I'm working on an app that records x,y,z accelerometer values and when subjecting the watch to extreme acceleration (a swing) I notice the x, and y acceleration seems to get stuck around ~30G.
Is this a hardware limitation of the watch sensors? I have a Apple Watch Series 7.
Below is the chart of the acceleration recording session.
Appreciate your insights! Joao
Are you using the High-Frequency Motion API that was introduced in 2023 (described here: https://developer.apple.com/videos/play/wwdc2023/10179/)? If so, you will need an Apple Watch Ultra or Series 8 or higher to capture motion and accelerometer data at the higher frequency mentioned in the video.
The problem isn't the frequency of data capture, it is the amount of the G force. Data is captured every 10ms (100Hz) the issue is how many G's (how much acceleration) can a watch measure.
In my post I see the graph flattens at 30G for X and Y when in fact it was subjected to more than that.
I've used an Apple Watch 7 for this experiment.
