- In this tutorial I explain how to use IMU with Raspberry Pi. Also, basic information about sensors used in IMU is explained.
Here is the project file

Excellent! As usual it is educational, concise and precise.
Hi cmtro!
I am glad if this video has helped you!
Great video!! I have one question left tho. What exactly is the difference between a IMU and a MEMS? Do they work together? Maybe you can help me to answer my question to get better understanding. Thanks a lot :-)
Hi Jonathan Edling!
Thanks for watching my video!
In my understanding, MEMS itself is a sensor (accelerometer, gyroscope). And IMU consists of several sensors (often MEMS sensors), circuit and a program. I also found an interesting article. I hope it will help you.

Thank you! Great article ❤
Can you use a BNO055 instead of the IMU that you use? If so what can I change in the python code to make it work for the BNO055? Thank you!
Hi SusDio!
Thanks for watching my video!
Yes, the code provided with my video should work with BNO055. Please refer to this page to use BNO055 libraries.

hey i am a little bit confused on how to use mpu9250 with raspberry pi4. i need to use it for keeping track on oriantation of my project rc car
Hi Akshat Singh!
Thanks for watching my video!
What problem exactly do you have with mpu9250?
Hi, do you think that signal could be more accurate using a raspberry instead of an esp32 wroom 32??? I need a very accurate X movement signal. Thanks
Hi Dj Kad aka MC!
I have never used esp32-wroom-32, so I cannot tell you for sure, but if the computational capabilities of these two devises are the same, I don’t think that there will be any difference.
Thanks. I think esp32 have enough resource. Probably i should focus on the MEMS chip specs. I'm starting with mpu6050. If i need more accurated signal i will buy a MPU9250 because has better performance. If it's not enough i will buy an expensive ADIS16470. It's a very important project
I got a question: can I use ubuntu os22.04 with imu bno055 this code be active?
Hi Tân Lê Thái!
Thanks for watching my video!
I think you can use bno055 with ubuntu22 using this library
rpi-lgpio.readthedocs.io/en/latest/
But the code provided with this tutorial is not applicable for ubuntu22.
it shows an error after the "pip3 install imufusion" i don't know why, help please
Hi Michelle HC!
Thanks for watching my video!
What kind of error do you have?
@@robotmania8896 go the same error, it says "ERROR: Could not find a version thta satisfies the requirement imfusion"
@@psamae I think it could be a python version problem. Which version of python are you using?
@@robotmania8896 I am on python 3
@@psamae Which version of python3 exactly? It seems that “imufusion” is provided only from python3.8.
