[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 Android/C++

Got this bought for Christmas to polar align my new smart. TelescopeWorked great used Velcro to attach downloaded app and used phone to set correct angleFantastic got perfect angle in seconds

Easy to use but the app was a bit fiddly. Works well

I think this product is fine for hobby-projects or applies where you do not need much precision at all. Certainly, it does not provide at a rate of 200hz, and the angle resoultion more than 0.2 degree. Wanted to measuse knee angle in the gait cycle-- too much repeated values where the imu is clearly moving.

Fantastic product, works exactly as described. I purchased the WT9011DCL sensor to measure body movement while assessing balance. It has worked perfectly. The sensor connected to an IOS app and I recorded data from the app. I had some minor technical issues which the team (Ms Ai Luo) from Wit-Motion swiftly helped me with.

Product is overall a very good one. Only the software that crashes from time to time, but the sensor itself is really good.

This is a nifty tiny little device that is a 9-axis gyroscope, angle and magnetometer sensor.The device is really small. It comes with a USB dongle and a short charging cable.The instructions describe how to download the app for android and IOS and also Windows. The app shows all the data and graphs in realtime and also historical information that is stored to your connected device.When installing the app you have to agree to a lot of terms and conditions and what information can be read from your phone etc. I'm a little bit sceptical of this especially when the device comes from China and how their privacy laws are well..... not private.However, the sensor is fantastic with a plethora of information. If you need to determine position, rotation, impact, direction etc then this is a a great device. You will just need to know how to harness the information for your application.4 stars.

This does what it says - it's easy to use and pair with the app on your phone. I'm trying to figure out a way to use it to more accurately record slope changes when making cycling videos, but I'm not there yet...
