[Bluetooth 5.0 Accelerometer+Inclinometer] WT9011DCL MPU9250 High-precision 9-axis Gyroscope+Angle(XY 0.2° Accuracy)+Magnetometer with Kalman Filter, Low-power 3-axis AHRS IMU Sensor for Arduino

The sensor works great, USB-C to charge, lasts all day it seems. Connects via bluetooth and its simple. The software that comes with it (via google drive) is good. The company support is great. I had different needs on the scales in the graphing software and they updated the software and sent me a personal link with the update I needed. You can't beat that. The output can be several container types and I can import that sensor data to most other software no problem via CSV or txt, etc, and even Open Office reads it fine in SpreadSheets for custom graphing as needed (images included). Their custom software has great features (see my first image of all the real time data streaming in and graphing). I use this to measure acceleration changes to understand relationships of vibration and coupling as a form of tactile response with audio and transducers.

Got it for a hobby project. The hardware device works well. Setting up the phone app was easy.Documentation is pretty lacking and the PC software was a little hard to set up, but i eventually got it.I was able to write a simple python program to connect via bluetooth and extract the data feed in real time.

Good sensor for acceleration but up to now, I haven't found a way to augment the resolution for the vibration I need to monitor.

Took off 1-star because App needs further work when it comes to display's chosen language. Too much is still in Mandarin, even when English is selected as language.As accelerometer it works in all 3-axis XYZ and rotation around those 3-axis.Not sure about what one menu selection is trying to show when it comes to moving differentiation.

The package is supposed to include a QR code that leads you right to the correct software. Mine did not. Nor could I find an app by searching the Google Play store despite what their website says. And there's no download section on their website. Very frustrating. Eventually I found a YouTube video which told me to click on a certain symbol on their website which led me to a list of apps that were in zip format. Apparently with motion has many versions of this accelerometer and none of the apps had my exact product number so I chose the closest one. I had to use two programs to unzip it and get it to run.The label on the device has a different product number than what shows up on the Bluetooth list. Needless to say if I wasn't a power user and very interested in getting this thing to run I would have given up by now. But after about an hour I got the thing loaded onto my Android 13 phone and it looks pretty good, however there's no way to set and fix the range setting on their chart even though there's a button to do that it's not functional. Without this feature it will be hard to compare acceleration plots from the various devices I wish to try.Update April 2024: I tried again to contact this company because I was unable to use the recorder or even set permissions for file access. To my surprise they responded immediately (and how rare is that these days) and fixed the problem. For that I had to bump them up to five stars.
