I'm interested in the accuracy of the accelerometer of CIQ devices. Since I can't find informations on that topic at all I did some experiments with my vivoactive hr and evaluated the sensor readings of Sensor.getInfo(). Seems like the resolution is fairly bad compared to the accelerometer readings of my 3 years old smartphone.
The data provided by CIQ has quite big discretization steps of 15 mg suggesting a total value range of 10 bit.
I'm wondering whether these limitations are due to the sensor hardware itself or the CIQ interface that artificially reduces the resolution? Is there any CIQ device with an accelerometer with higher resolution/accuracy or do all CIQ devices share the same sensor characteristics? I need quite accurate sensor readings for my app.
An official statement on that topic would be great.
