Understanding the raw output of MPU-6050
Anudeep last edited by
I have a small doubt regarding the raw values given by MPU 6050.
I am getting 6 raw values from the MPU 6050 sensor!
I have given a default sensitivity of +/- 2g.
What exactly each value mean? Is it like, voltage values across each axis or capacitance values or the acceleration values itself.
But for me they doesn't mean anything. I am getting some values above 1000, some of them in negative and some doesn't go beyond +/- 250.
So, can you explain me in detail what does those value mean in physical parameters and their units?

Hi @Anudeep ,
MP66050 is a Gyroscope + Accelerometer + Temperature Sensor Module ,
The 3 Axis Gyroscope is used to detect rotational velocity along the X, Y, Z axes as shown in the below figure.

The full-scale range of output is +/- 250, +/- 500, +/- 1000, +/- 2000 , and that is the angular velocity represented in units of rotations per minute (RPM), or degrees per second (°/s). The three axes of rotation are either referenced as x, y, and z, or roll, pitch, and yaw.
Accelerometers are devices that measure acceleration, which is the rate of change of the velocity of an object, it can be used to detect the angle of tilt or inclination along the X, Y and Z axes as shown in below figure.

They measure in meters per second squared (m/s2) or in G-forces (g). A single G-force for us here on planet Earth is equivalent to 9.8 m/s2, but this does vary slightly with elevation (and will be a different value on different planets due to variations in gravitational pull)
Hey guys, we are thrilled to announce the speaker Mr. Brian Douglas for our upcoming event organised by HackClub TIST as part of Hacktoberfest 2020. He will guide you through GitHub and the importance of Open Source contributions.
Mr. Brian Douglas has been working as a Staff Developer Advocate at GitHub for the past three years and was fully on-board with us when we contacted him about the event.
We at Hackclub TIST strongly believe in the power of collaboration and how even the smallest guidance can have a huge impact in the long run.
So register now at http://hackclubtist.tech/hacktoberfest and lets git learning (pun intended).

@Anudeep Thanks a lot m8, I actually made a very silly mistake of including the https:// while entering FIREBASE_HOST, where I must have entered the Domain name alone and removed the https:// extension.
Thanks again for replying that quick. Cheers.
Hello @Palani, In the Firebase, there are two types of storage,Cloud Firestore (Very recent one & NoSQL database) Realtime Database (To which we upload the data using NodeMCU)
In the Arduino Code, you can see that there is a variable named FIREBASE_AUTH.
This variable should be assigned to the Database secret. This you can find in Project Settings -> Service accounts -> Database Secrets.
My mistake is, i have mistakenly assigned thay to Web API key. This is found at Project Settings -> General.
The error can also occur when u don't initialise a proper realtime database in Firebase. (This is not my case).
@Anudeep Hello Anudeep could you please help me out by elaborating the fix to get rid of that error?
Thanks in advance.
