MPU6050 Accelerometer and Gyroscope Sensor

IoT 0 Comments Like: 0

🧠 What is MPU6050?

The MPU6050 is a 6-axis motion tracking device made by InvenSense. It combines:

✅ 3-axis accelerometer (measures acceleration)
✅ 3-axis gyroscope (measures rotation)
✅ Communicates via I2C protocol
✅ Built-in Digital Motion Processor (DMP)

🧾 What Can It Measure?

Sensor	Measures	Unit
Accelerometer	Acceleration on X, Y, Z	m/s² or g
Gyroscope	Rotation on X, Y, Z axes	°/sec
DMP	Calculates pitch, roll, yaw	Degrees

🧰 Components Required

Component	Description
ESP32 Board	(Any Devkit)
MPU6050 Module	GY-521 or equivalent
Jumper Wires	Male-to-female preferred
Arduino IDE	With libraries installed

🔌 Wiring MPU6050 with ESP32

MPU6050 Pin	ESP32 Pin	Function
VCC	3.3V	Power
GND	GND	Ground
SDA	GPIO 21	I2C Data
SCL	GPIO 22	I2C Clock

MPU6050 works with 3.3V and 5V, but use 3.3V for safety with ESP32.

🧰 Step-by-Step Setup in Arduino IDE

✅ Step 1: Install Libraries

Open Arduino IDE
Go to Sketch > Include Library > Manage Libraries
Install:
