We have two measurements of the angle from two different sources. The measurement from accelerometer gets affected by sudden horizontal movements and the measurement from gyroscope gradually drifts away from ac
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 ...
Serial.println ("Gyroscope"); } void loop () { endtime = micros(); // End time for the current Measurement if (firstcall) { firstcall=false; } else { dt = (float)(endtime - starttime)/1000000; // Get time beetween measurements gyro_rateX=gyro.readX_DegPerSec(); // Current ...
The unit of measurement for acceleration is meter per second squared (m/s^2). However, accelerometer sensors usually express the measurements in “g” or gravity. One “g” is the value of the earth gravitational force which is equal to 9.8 meters per second squared. So, if we have an ...

Inertial Measurement Unit (IMU) Essentially IMU is used to calculate the angle between the quadcopters each axis and the ground. Normally IMU used inside quadcopters must have at least two elements - an accelerometer and a gyroscope. Not going too much into the details on how IMUs are made...
Inertial measurement unit (IMU) modules like the GY-87 combine many sensors into a single package, such as the MPU6050 accelerometer/gyroscope, the HMC5883L magnetometer, and the BMP085 barometric pressure sensor. Hence, the GY-87 IMU MPU6050 is an all-in-one 9-axis motion tracking module ...
We can operate the device with just a single button. Once we power the device we need to select the unit of measurement. By pressing the button we can toggle through the units, and if we press and hold the button for a while we will get into the first program. Here we can measure ...
