ESP32 with MPU-6050 Accelerometer, Gyroscope and Temperature Sensor (Arduino)

In this guide you’ll learn how to use the MPU-6050 accelerometer and gyroscope module with the ESP32. The MPU-6050 IMU (Inertial Measurement Unit) is a 3-axis accelerometer and 3-axis gyroscope sensor. The accelerometer measures the gravitational acceleration and the gyroscope measures the rotational velocity. Additionally, this module also measures temperature. This sensor is ideal to determine the orientation of a moving object.

ESP32 MPU-6050 Module Accelerometer Gyroscope Temperature Sensor Arduino

We have a similar guide for the ESP8266: ESP8266 NodeMCU with MPU-6050 Accelerometer, Gyroscope and Temperature Sensor (Arduino)

In this guide we’ll cover two examples:

  1. Get gyroscope, acceleration and temperature readings (Serial Monitor)
  2. Display gyroscope and acceleration readings on OLED display

Introducing the MPU-6050 Gyroscope Accelerometer Sensor

The MPU-6050 is a module with a 3-axis accelerometer and a 3-axis gyroscope.

MPU-6050 Module Accelerometer Gyroscope Temperature Sensor

The gyroscope measures rotational velocity (rad/s), this is the change of the angular position over time along the X, Y and Z axis (roll, pitch and yaw). This allows us to determine the orientation of an object.

Roll Pitch Yaw Angles

The accelerometer measures acceleration (rate of change of the object’s velocity). It senses static forces like gravity (9.8m/s2) or dynamic forces like vibrations or movement. The MPU-6050 measures acceleration over the X, Y an Z axis. Ideally, in a static object the acceleration over the Z axis is equal to the gravitational force, and it should be zero on the X and Y axis.

Using the values from the accelerometer, it is possible to calculate the roll and pitch angles using trigonometry. However, it is not possible to calculate the yaw.

We can combine the information from both sensors to get more accurate information about the sensor orientation.

MPU-6050 Pinout

Here’s the pinout for the MPU-6050 sensor module.

VCCPower the sensor (3.3V or 5V)
GNDCommon GND
SCLSCL pin for I2C communication (GPIO 22)
SDASDA pin for I2C communication (GPIO 21)
XDAUsed to interface other I2C sensors with the MPU-6050
XCLUsed to interface other I2C sensors with the MPU-6050
AD0Use this pin to change the I2C address
INTInterrupt pin – can be used to indicate that new measurement data is available

Preparing Arduino IDE

We’ll program the ESP32 board using Arduino IDE. So, make sure you have the ESP32 add-on installed. Follow the next tutorial:

If you prefer using VS Code + PlatformIO IDE, follow the next guide:

Installing Libraries

There are different ways to get readings from the sensor. In this tutorial, we’ll use the Adafruit MPU6050 library. To use this library you also need to install the Adafruit Unified Sensor library and the Adafruit Bus IO Library.

Open your Arduino IDE and go to Sketch > Include Library > Manage Libraries. The Library Manager should open.

Type “adafruit mpu6050” on the search box and install the library.

Install Adafruit MPU6050 Gyroscope Accelerometer Sensor Library Arduino IDE

Then, search for “Adafruit Unified Sensor”. Scroll all the way down to find the library and install it.

Install Adafruit Unified Library Arduino IDE

Finally, search for “Adafruit Bus IO” and install it.

Install Adafruit Bus IO Library Arduino IDE

After installing the libraries, restart your Arduino IDE.

If you’re using VS Code with PaltformIO, copy the following lines to the platformio.ini file.

lib_deps = adafruit/Adafruit MPU6050 @ ^2.0.3

How the Code Works

Start by including the required libraries for the MPU-6050 sensor: Adafruit_MPU6050 and Adafruit_Sensor.

#include <Adafruit_MPU6050.h>
#include <Adafruit_Sensor.h>

Create an Adafruit_MPU6050 object called mpu to handle the sensor.

Adafruit_MPU6050 mpu;

setup()

In the setup(), initialize the serial monitor at a baud rate of 115200.

Serial.begin(115200);

Initialize the MPU-6050 sensor.

if (!mpu.begin()) {
  Serial.println("Sensor init failed");
  while (1)
    yield();
}

Set the accelerometer measurement range:

mpu.setAccelerometerRange(MPU6050_RANGE_8_G);

Set the gyroscope measurement range:

mpu.setGyroRange(MPU6050_RANGE_500_DEG);

Set the filter bandwidth:

mpu.setFilterBandwidth(MPU6050_BAND_5_HZ);

loop()

In the loop() we’ll get sensor readings and display them in the Serial Monitor.

First, you need to get new sensor events with the current readings.

sensors_event_t a, g, temp;
mpu.getEvent(&a, &g, &temp);

Finally, print the readings. For the acceleration:

  • a.acceleration.x: gets acceleration on the x axis;
  • a.acceleration.y: gets acceleration on the y axis;
  • a.acceleration.z: gets acceleration on the z axis.

The acceleration is measured in meters per second square (m/s2)

Serial.print("Acceleration X: ");
Serial.print(a.acceleration.x);
Serial.print(", Y: ");
Serial.print(a.acceleration.y);
Serial.print(", Z: ");
Serial.print(a.acceleration.z);
Serial.println(" m/s^2");

To get gyroscope readings:

  • g.gyro.x: gets angular velocity on the x axis;
  • g.gyro.y: gets angular velocity on the y axis;
  • g.gyro.z: gets angular velocity on the z axis.

The angular velocity is measured in radians per seconds (rad/s).

Serial.print("Rotation X: ");
Serial.print(g.gyro.x);
Serial.print(", Y: ");
Serial.print(g.gyro.y);
Serial.print(", Z: ");
Serial.print(g.gyro.z);
Serial.println(" rad/s");

Finally, print the temperature – it is measured in Celsius degrees. To access the temperature reading use temp.temperature.

Serial.print("Temperature: ");
Serial.print(temp.temperature);
Serial.println(" degC");

New sensor readings are displayed every 500 milliseconds.

delay(500);

Demonstration

Upload the code to your ESP32 board. Go to Tools > Board and select the ESP32 board you’re using. Go to Tools > Port and select the port your board is connected to. Then, click the Upload button.

Open the Serial Monitor at a baud rate of 115200, press the on-board RST button. The sensor measurements will be displayed.

Move the sensor orientation and see the values changing accordingly.

MPU-6050 Sensor Readings Serial Monitor Arduino IDE

Sensor Calibration

Ideally, when the sensor is static, the gyroscope values should be zero on all axis, which doesn’t happen in our case. When the sensor is static, these are the gyroscope values we get:

  • x: 0.06 rad/s
  • y: -0.02 rad/s
  • z: 0.00 rad/s

On practical applications, you need to take the error into account and correct the values in the code to get more accurate readings.

The same happens for the acceleration values. The acceleration on the z axis should be closer to the gravitational force (9,8 m/s2) and it should be closer to zero on the x and y axis. In our case, these are the approximate values we get when the sensor is static:

  • x: 0.71 m/s2
  • y: 0.28 m/s2
  • z: 9.43 m/s2

How the Code Works

Start by including the required libraries for the MPU-6050 sensor and for the OLED display.

#include <Adafruit_MPU6050.h>
#include <Adafruit_SSD1306.h>
#include <Adafruit_Sensor.h>

Create an Adafruit_MPU6050 object called mpu to handle the sensor.

Adafruit_MPU6050 mpu;

Create an Adafruit_SSD1306 object called display to handle the OLED display. This is for a display with 128×64 pixels.

Adafruit_SSD1306 display = Adafruit_SSD1306(128, 64, &Wire);

setup()

In the setup(), initialize the serial monitor at a baud rate of 115200.

Serial.begin(115200);

Initialize the MPU-6050 sensor.

if (!mpu.begin()) {
  Serial.println("Sensor init failed");
  while (1)
    yield();
}

Initialize the OLED display.

// SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally
if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) { // Address 0x3C for 128x64
  Serial.println(F("SSD1306 allocation failed"));
  for (;;)
    ; // Don't proceed, loop forever
}
display.display();

Set the font size and color for the display.

display.setTextSize(1);
display.setTextColor(WHITE);
display.setRotation(0);

loop()

In the loop() is where we’ll get the sensor readings and display them on the OLED.

Start by creating events for each measurement, accelerometer, gyroscope and temperature.

sensors_event_t a, g, temp;

Get new sensor readings.

mpu.getEvent(&a, &g, &temp);

Clear the display in each loop() to write new readings.

display.clearDisplay();

Set the display cursor to (0,0) – the upper left corner. It will start writing text from that location.

display.setCursor(0, 0);

The following lines print the accelerometer readings in the Serial Monitor.

Serial.print("Accelerometer ");
Serial.print("X: ");
Serial.print(a.acceleration.x, 1);
Serial.print(" m/s^2, ");
Serial.print("Y: ");
Serial.print(a.acceleration.y, 1);
Serial.print(" m/s^2, ");
Serial.print("Z: ");
Serial.print(a.acceleration.z, 1);
Serial.println(" m/s^2");

The following lines display the acceleration x, y an z values on the OLED display.

display.println("Accelerometer - m/s^2");
display.print(a.acceleration.x, 1);
display.print(", ");
display.print(a.acceleration.y, 1);
display.print(", ");
display.print(a.acceleration.z, 1);
display.println("");

Display the gyroscope readings on the Serial Monitor.

Serial.print("Gyroscope ");
Serial.print("X: ");
Serial.print(g.gyro.x, 1);
Serial.print(" rps, ");
Serial.print("Y: ");
Serial.print(g.gyro.y, 1);
Serial.print(" rps, ");
Serial.print("Z: ");
Serial.print(g.gyro.z, 1);
Serial.println(" rps");

Finally, print the gyroscope readings on the display.

display.println("Gyroscope - rps");
display.print(g.gyro.x, 1);
display.print(", ");
display.print(g.gyro.y, 1);
display.print(", ");
display.print(g.gyro.z, 1);
display.println("");

Lastly, call display.display() to actually show the readings on the OLED.

display.display();

New readings are displayed every 100 milliseconds.

delay(100);

Wrapping Up

The MPU-6050 is an accelerometer and gyroscope. It measures acceleration on the x, y and z axis as well as angular velocity. This module also measures temperature.

This sensor modules communicates via I2C communication protocol. So, the wiring is very simple. Just connect the sensor to the ESP32 default I2C pins.

In this tutorial you’ve learned how to wire the sensor and get sensor readings. We hope you’ve found this getting started guide useful. We have guides for other popular sensors:

  1. Hello,
    great project again. But I got one little thing about the I2C connections. There should be two 4,7 k resistors between plus and the SDA and SCL wires to have a
    trouble-free system.
    I like your projects very much because there are all trouble free and working.

  3. Fantastic project, as usual. Thanks.
    Just a thought – I find it hard to read the OLED screen (Mine is a 128 x 64), and my eyesight is not too good recently😊
    It would be fantastic if you could display the data on a TFT display – say 2,8″, which will present much more readable data.

  4. I find the sketches very interesting and instructive. Especially the commands for the for low pass fillter are important for me.
    My problem: Sometimes the sketch works. But most of the time my gyroscope sensors (4 different ones) are not recognized. (“Failed to find MPU6050 chip”) An I2C scan returns the address 0x68. So the scan finds the gyroscope. Other sketches (directly via wire.h ) detect the gyroscope and work. I tried to start the sensor with
    mpu.begin( uint8_t i2c_addr =0x68, TwoWire *wire=&Wire, int32_t sensorID=0);
    but when transferring to the ESP32 I get the error message:
    expected primary-expression before ‘i2c_addr’.
    What can I do? Greetings from germany.

    • I had the same issue. To debug it, I added some print statements to the conditional checks in the begin method in the MPU6050 library, and found that the chip_id wasn’t matching the MPU6050_DEVICE_ID in the MPU6050 header file. MPU6050_DEVICE_ID was defined as 0x68, but I was getting a returned chip_id of 0x72.

      I changed the value of the define and it started working.

  12. Hello! Please advise how to have two of this MPU6050-ESP32 module sending data simultaneously to a laptop. I need data from the two IMU sensors at the same time to the laptop. Thanks!

  13. Hi. I am using the MPU6050 in interrupt mode. I want it to interrupt my ESP32 when movement is detected. I don’t need to read anything from the MPU6050 when that interrupt happens, but just get the message that there was movement.

    This works under normal circumstances. However, if I turn on cycle mode, which makes the MPU6050 go into a low power mode and only cycle at 1.25Hz or at any of the cycle rates:

    MPU6050_CYCLE_1_25_HZ
    MPU6050_CYCLE_5_HZ, ///< 5 Hz
    MPU6050_CYCLE_20_HZ, ///< 20 Hz
    MPU6050_CYCLE_40_HZ
     Then the MPU6050 will not interrupt when moved. If I take the MPU out of that mode, interrupts start happening again.

    Can anyone verify that this is normal, or if I am doing something wrong? It seems to me that the low power cycle mode should be well suited for use with the interrupt, but that does not seem to be the case.

    Thank you.

  14. if and else statement should be inverted in the setup loop

    if (mpu.begin()) {
    Serial.println(“MPU6050 Found!”);
    while (1) {
    delay(10);
    }
    }
    else{
    Serial.println(“Failed to find MPU6050 chip”);
    }

  15. Sara, I am trying to use the MPU6050 with the TTGO OLED LoRa ESP32 board. The Adafruit library for the OLED uses non-standard pins for its I2C bus. I’ve been struggling to get two instances of Wire() defined so I can use the Adafruit library and at the same time have another I2C function using pins 21/22. I’ve been successful getting a second random WireMPU() function to work and talk to the MPU chip, but somehow my TwoWire constructor doesn’t like to build another one for the OLED. Plus, I don’t see in the OLED.cpp how to pass the address of the second Wire() function to the OLED code when I do the OLED.begin(….) .

  19. Adafruit_MPU6050 mpu;
    Adafruit_SSD1306 display = Adafruit_SSD1306(128, 32, &Wire);

    Change your Code for this Line. It will look as you like it.

  20. Failed to find MPU6050 chip – I have the same error with THIS (adafruit) library

    With MPU6050 lib by Electronic Cats – I can run example sketch in 1 click

    device ID from i2c scanner is the same 0x68

    Could you or somebody else make this sketch based on Electronic Cats MPU6050 lib?

  21. Hello and thank you for this perfect tutorial!
    I have a question. How can I receive the plot related to MPU-6050 data on the webserver page that this project brought numeric data and the 3D movement of the sensor?
    I would be glad if someone could answer this for me causze I’m a new learner.
    Thanks a lot in advance.
