MPU-6050 IMU Sensor Module – 6 Degrees of Freedom Gyroscope + Accelerometer

MPU-6050 IMU Sensor Module – 6 Degrees of Freedom (Gyroscope + Accelerometer)

The MPU-6050 is a highly integrated 6-axis Inertial Measurement Unit (IMU) that combines a 3-axis gyroscope and a 3-axis accelerometer on a single chip. This powerful sensor module is widely used in robotics, drones, wearable technology, motion tracking devices, gaming controllers, and many other applications requiring precise motion sensing and orientation detection.

Key Features and Benefits

  • 6 Degrees of Freedom (DOF): Measures rotational velocity (gyroscope) and linear acceleration (accelerometer) simultaneously across three axes (X, Y, Z), enabling accurate 3D motion sensing.

  • Integrated Digital Motion Processor (DMP): Offloads complex sensor fusion calculations from your microcontroller by processing raw sensor data internally, providing processed and stabilized motion data.

  • Wide Operating Voltage Range: Compatible with 2.5V to 3.6V power supply, many breakout boards support 5V for easy integration with Arduino and other microcontrollers.

  • High Sensitivity & Configurable Ranges: Adjustable gyroscope ranges (±250, ±500, ±1000, ±2000 dps) and accelerometer ranges (±2g, ±4g, ±8g, ±16g) let you optimize precision or range depending on your project needs.

  • I²C Interface: Supports standard I²C communication (up to 400kHz) for easy connection to microcontrollers such as Arduino, ESP32, Raspberry Pi, and more.

  • Compact Size: Small module footprint suitable for space-constrained projects and embedded systems.

  • Built-in Temperature Sensor: Provides temperature data to help calibrate measurements and maintain accuracy.

  • Wide Operating Temperature Range: Works reliably in harsh environments from -40°C to +85°C.

How to Use the MPU-6050 with Arduino

  1. Install the Arduino Library:
    Use the popular “MPU6050” or “MPU6050_light” library available on GitHub or through Arduino Library Manager for easy interfacing and calibration.

  1. Basic Code Example:

cpp
CopyEdit
#include <Wire.h>
#include <MPU6050.h>

MPU6050 mpu;

void setup() {
  Serial.begin(9600);
  Wire.begin();
  mpu.initialize();

  if (mpu.testConnection()) {
    Serial.println("MPU6050 connected successfully");
  } else {
    Serial.println("MPU6050 connection failed");
  }
}

void loop() {
  int16_t ax, ay, az;
  int16_t gx, gy, gz;

  mpu.getAcceleration(&ax, &ay, &az);
  mpu.getRotation(&gx, &gy, &gz);

  Serial.print("aX = "); Serial.print(ax);
  Serial.print(" | aY = "); Serial.print(ay);
  Serial.print(" | aZ = "); Serial.print(az);
  Serial.print(" | gX = "); Serial.print(gx);
  Serial.print(" | gY = "); Serial.print(gy);
  Serial.print(" | gZ = "); Serial.println(gz);

  delay(500);
}
