Movement of a device in XY.

I had a device that need to record data then plot the location. What type of mems sensor should I use?

Will it give the location or just reference.

Hi @ChawCS​ ,

the state of the art for plotting the location of a device make use of GPS modules because MEMS motion sensors are not able to provide data that can be analysed to plot a position in a 2/3D environment with enough accuracy.

Anyway, if you would like to research how accurate the plot from MEMS sensors data can be, you can try any accelerometer, like LIS2DW12, or even a 6-axis module, that can help with gyroscope data, like LSM6DSOX.

does this help you?

Hi Niccolo,

As this device (mobile car) will be in-house, do you think GPS can do the job?

Think a reference distance will do, mean the device move left, right. As it is to guide a curve line, as in a circle.

Hi @ChawCS​,

I did not kept into consideration the distances you have to work with. for a precise positioning of this kind I don't think GPS is suitable.

So I would try to use a LSM6DSOX (6-axis module) to try to solve this problem. Maybe you will not have a perfect positioning, but, with the right references around the device, it can be done.
