What is MPU 6050？

MPU 6050 contains a 3-axis gyroscope as well as a 3-axis accelerometer which allows measurement of both the parameters independently around the same axes. Thus, it eliminates the issue regarding cross-axis errors using individual sensors. In this work, MPU 6050 IC is used to help in balancing the flight of the quadcopter and maintain its flight dynamics.

WHERE TO USE MPU-6050?

MPU 6050 are used in self-balancing robots, UAVs, smartphones, and more. Motion sensor MPU-6050 help us to get the position of an object attached to the sensor in three-dimensional space. These values are in terms of angular positions of the subjected object. All devices which required orientation information like smartphones, wearable gadgets and modern game consoles uses MPU-6050.
