Introduction

10 DOF Mems IMU Sensor V2.0

At the beginning,the inertial measurement unit is an electronic device that measures and reports on a craft's velocity, orientation, and gravitational forces, using a combination of accelerometers,gyroscopes, and magnetometers. Now IMUs are commonly used in the Human-computer interaction(HCI), navigational purposes and balancing technology used in the Segway Personal Transporter as we all known.

Version Upgrade: V2.0 has upgraded the barometer sensor IC to BMP280.

Sample Code 1

Please download following library first.


#include <FreeSixIMU.h>
#include <FIMU_ADXL345.h>
#include <FIMU_ITG3200.h>

#include <Wire.h>

float angles[3]; // yaw pitch roll

// Set the FreeSixIMU object
FreeSixIMU sixDOF = FreeSixIMU();

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

  delay(5);
  sixDOF.init(); //begin the IMU
  delay(5);
}

void loop() {

  sixDOF.getEuler(angles);

  Serial.print(angles[0]);
  Serial.print(" | ");
  Serial.print(angles[1]);
  Serial.print(" | ");
  Serial.println(angles[2]);

  delay(100);
}

Open the arduino IDE serial monitor, you will get Yaw; Pitch; Roll value:
