MPU6050 How to interpret the data

Using Arduino Sensors
1

I'm trying to monitor vibrations and I have an MPU6050 I follow a code I found but i don't know how to interpret the data I got

Here is the code

int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ; //Variables

void setup(){

Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B); // PWR_MGMT_1 register
Wire.write(0); // set to zero (wakes up the MPU-6050)
Wire.endTransmission(true);

Serial.begin(9600);
}

void loop(){

Wire.beginTransmission(MPU_addr);
Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H)
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr,14,true); // request a total of 14 registers

AcX=Wire.read()<<8|Wire.read(); // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)
AcY=Wire.read()<<8|Wire.read(); // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
AcZ=Wire.read()<<8|Wire.read(); // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)

Tmp=Wire.read()<<8|Wire.read(); // 0x41 (TEMP_OUT_H) & 0x42 (TEMP_OUT_L)

GyX=Wire.read()<<8|Wire.read(); // 0x43 (GYRO_XOUT_H) & 0x44 (GYRO_XOUT_L)
GyY=Wire.read()<<8|Wire.read(); // 0x45 (GYRO_YOUT_H) & 0x46 (GYRO_YOUT_L)
GyZ=Wire.read()<<8|Wire.read(); // 0x47 (GYRO_ZOUT_H) & 0x48 (GYRO_ZOUT_L)

Serial.print("AcX = "); Serial.print(AcX);
Serial.print(" | AcY = "); Serial.print(AcY);
Serial.print(" | AcZ = "); Serial.print(AcZ);
Serial.print(" | Tmp = "); Serial.print(Tmp/340.00+36.53); //equation for temperature in degrees C from datasheet
Serial.print(" | GyX = "); Serial.print(GyX);
Serial.print(" | GyY = "); Serial.print(GyY);
Serial.print(" | GyZ = "); Serial.println(GyZ);

delay(100);

The output values are explained in the MPU6050 data sheet.

Please use code tags when posting code, as described in "How to use this forum".

That code doesn't compile. Please post complete code and use code tags! (that's the </> button in the editor).

Have you read the description of the acceleration and gyro registers in the datasheet? The acceleration depends on the ACCEL_FS register value while the gyro output depends on the FS_SEL register. With the highest values in those registers the acceleration is a 16 bit integer with a range of +/-8g and the gyro is a 16bit integer with a range of +/- 2000°/s.

Hello,

Sorry I didn't post it in the good format.

Thanks for your reply, I follow the MPU60X0 datasheet and divide my data by the sensitivity acoording to the range and I got nice data now
