If you are searching for a sensor that can control the motion of your Robot, Drone, RC car, or some other things like that then this sensor might be the right choice for you. Because, this sensor encourages to measure displacement, velocity, acceleration, orientation, and some other motion-related parameters of the device. Inside a module, there is a Digital Motion Processor which is adequate to perform complex calculations or computations.
An Overview of MPU6050
The MPU-6050 is the 3 axis gyroscope and 3 axis accelerometer. The gyroscope estimates the rotational gravity. While the accelerometer gauges gravitational creation. Thus, it calculates the acceleration over the X, Y, and Z-axis. Using the values of the accelerometer of this sensor, one can calculate the angles by trying trigonometry. The sensor used the idea of Coriolis force Primarily; the sensor converts the rotational rate into an electrical signal. Further, it senses the angular velocity. Also, it detects the angular velocity generated by the sensor’s movement. It detects the vibration that is generated by any external elements and converts it into electrical signals
Working of Accelerometer
By measuring the gravity, the accelerometer comprehends which direction is down towards the Earth or how speedily the board is speeding up in three-dimensional space. The accelerometer measures the vibration of any object. Practically, the vibrations of any object cause the piezoelectric effect. Thus, t converts these mechanical motions into an electrical signal. An accelerometer converts mechanical energy into electrical energy.
How Gyroscope Works?
The gyroscope controls the twist and space A gyroscope is used to measure the rotation of any particular axis. It comprises the drive arm which is attached to the sensing element. The arm creates the motion in the sensing element which produces the angular velocity. It then converted this angular velocity into electrical signals. Hence gyroscope detects and estimates the motion of the objects.

Applications of MPU6050
Self Balancing Robots
For the navigation of self-balancing Robots. The sensor determines the exact location of the robot in three-dimensional space. And, by combining the values of accelerometer and gyroscope data, one can obtain very specific information defining the orientation of the sensor.
The MPU6050 gyroscope connects when interfaced with the microcontroller or microprocessor of the drone, it will read and filter to get an accurate angle. The
results of the angle used as commands to move the drone.
Humanoid Robot Control System
MPU6050 sensor transmits the data serially. The microcontroller note and stores this data, which then gives the corresponding data to the transceiver of the robot, depending on the orientation of the MPU6050 sensor.
