MPU6050 Sensor – Pin Diagram, Working Principle and Applications Explained

Introduction

The MPU6050 is a Micro-Electro-Mechanical System (MEMS) sensor that combines a three-axis accelerometer and a three-axis gyroscope into a single module. It is capable of measuring acceleration, angular velocity, orientation, displacement, and motion.

The MPU6050 supports the measurement of velocity, orientation, and acceleration in all three dimensions. It includes an internal 16-bit Analog to Digital Converter (ADC) that allows the capture of precise motion data in real time.

Magnetometers and microcontroller-based systems can be easily interfaced with the MPU6050 through the I²C communication protocol. Due to this capability, it is widely used as a 6-axis motion tracking device in embedded and IoT applications.
