ESP32 Web Server with MPU-6050 Accelerometer and Gyroscope (3D object representation)

[@romycruz4498]

Thanks Rui. You're great. when I retire from my job, i am looking into making projs. as a hobby and a small business to earn for a living while getting old. I have also downloaded many of your tutorials. Thanks - Romy-Philippines.

[@Kaka-zs4cp]

Hey, your ascent is getting better! Let me give you a tip, angular + webpack + websocket will make a weightless interface to the esp32 board! It’s just perfect

[@Kaka-zs4cp]

And gzip the files ! Everything gets super fast if you do

[@RuiSantosdotme]

You can find the complete project details (schematics + source code) on my blog ► RandomNerdTutorials.com/esp32-mpu-6050-web-server/ Build a web server with the ESP32 to display readings from the MPU-6050 accelerometer and gyroscope sensor. We’ll also create a 3D representation of the sensor orientation on the web browser. The readings are updated automatically using Server-Sent Events and the 3D representation is handled using a JavaScript library called three.js.

[@paulvint]

That's a great demonstration! Fortunate timing for me too, as I recently ordered some MPU6050s for testing for a project. :)

[@RuiSantosdotme]

Happy to know it was published in good timing!

[@piconano]

The MPU-6050 has a DSP built in to it. I think it can run some sort of Kalman filter on the raw sensor data. I think the old Wii controller from 2008'ish used them. The gyros need to be reset when the accelerometers read no change in acceleration, and the gyros see no rotational changes, or something like that. That's to compensate for gyro drift. It gets too complicated for me. I tried to follow the ArduPilot code, and gave up in one day! The quitting force is strong in me...

[@RuiSantosdotme]

Thank you, we will look into more detail in the upcoming weeks!

[@carlosbugs]

its a coll project. a great approach to demonstrate the capabilities of the magnetometer + gyroscope sensor. keep doing good things like that :)

[@emmetray9703]

Are you using MPU's internal DMP(Digitan Motion Processor) or just reading raw datas from a registers?

[@batugunduz3950]

It looks like raw data. He probably just integrates the angular rate values and doesnt even touch the accelerometer as he needs to reset the position from time to time

[@scgsantos22]

@@batugunduz3950 Yes. For this example, we just integrated the angular rate values to get the position. We didn't use the accelerometer values because the result was worse. And, yes, from time to time, there's the need to reset the position because the sensor drifts a bit and the error accumulates over time.

Hi Rui. I appreciate your projects, they helped me a lot. Can you suggest me how to transfer data wirelessly every 10 milliseconds without stuttering (ECG data)? I tried to use websockets but sometimes it was shuttering. Will using SSE fix the problem? Or is it better to send the collected data in array (eg. from 1 second interval) to the MySQL database? (Data can be buffered, I don't need live broadcast.) Is it possible to draw a graph from an array of data stored in one cell or each value must be stored in a new database cell? Thank you for your work.

Great project, Rui. Apparently I haven't used the ESPAsyncWebserver class before. I have the esp32 1.04 core installed, but the md5.h is missing for the ESPAsyncWebServer-master/src/WebAuthentication.cpp. Any ideas? I believe it should be in the core.

[@hwhhamp9858]

Hi, as the drift is always related to one of the axis, is it possible to add 2 more MPUs with always complementary directions? With this you would be able to make a 2 out of 3 calculations and can overcome the drift. Not sure, whether this idea is correct.

[@filipecoelho9855]

I think that the drift is because of gravity acceleration, so it's always on the same axis, don't matter how you position the IMUs.

This is Excellent work! Thank you. Are there any easy CSS or HTML editors, that I can use to change the web page? Example if i wanted to change the font, the size or location on the page? This is a much more general question. i often need to read two i2c sensors. They are on different addresses, same bus. How easy is it to just add in the script portion for say a Time of Flight distance sensor (VL53L0X). And just at the distance to the webpage? I guess I'm asking you already built 90% of this, is it just adding the VL53L0X in the script and passing it to the HTML? So, you have a robotic arm. The 6050 can read the angles, and you can read the distance via the VL53L0X to the bed.

[@scgsantos22]

Hi. If you have some basic knowledge you can easily change the colors, font, size, etc... By just following some basic HTML and CSS tutorials you might be able to do that. We have a new eBook that shows how to build your web servers from scratch including all the HTML, CSS and JavaScript files: randomnerdtutorials.com/build-web-servers-esp32-esp8266-ebook/ We also have many free tutorials with the ESP32 that you might find useful for your project: randomnerdtutorials.com/projects-esp32/ As for the sensors, it is easy to add another sensor. You might want to take a look at this tutorial:randomnerdtutorials.com/esp32-web-server-sent-events-sse/ Then, you might be able to easily adapt it to your case. At the moment, we don't have any tutorials with the VL53L0X sensor. I hope this helps. :)

hi, i don‘t know if you can see my comment, but if you could answer i would really appreciate it! I have followed your tutorials step by step from hier: Visualize Your Sensor Readings from Anywhere in the World (ESP32/ESP8266 + MySQL + PHP) kzbin.info/www/bejne/l2KYZ2qsobiJeZo and everything went well until step4, when i enter the page of esp-chart.php, it shows access denied for user (password yes) . So i though maybe i should start from the beginning again, then i deleted the old database, file manger etc and created all of them again. But it come out no matter what i write, the website didn‘t change. like even if i give a wrong username in post-data.php. and change the echo from „no data posted with http post“ into „hahaha“, the website still shows no data posted with http post. what should i do ? thank you so much!

if you see something like this "shows access denied for user", your database user might not have the proper permissions to access the database. Make sure it has all permissions enabled.
