MPU6050 accelerometer gyroscope

The MPU-6050 is a highly popular, low-cost 6-Axis Inertial Measurement Unit (IMU) that integrates a 3-axis accelerometer, a 3-axis gyroscope, and a temperature sensor onto a single silicon chip. Manufactured by InvenSense, it is widely used in DIY electronics, robotics, drones, smartphones, and self-balancing platforms because of its precision and ease of use.Core Technical SpecificationsThe module uses 16-bit analog-to-digital converters (ADCs) for each of its channels, allowing it to capture X, Y, and Z tracking data simultaneously with high precision.

• Operating Voltage: 3V to 5V (Most breakout boards like the GY-521 include an onboard voltage regulator).
• Communication Protocol: Standard IC serial bus interface.
• Default IC Addresses: 0x68 (default) or 0x69 (if the AD0 pin is pulled high).
• Gyroscope Range: Programmable full-scale ranges of 250, 500, 1000, and 2000/sec.
• Accelerometer Range: Programmable full-scale ranges of 2g, 4g, 8g, and 16g.

Key Internal Components

1. 3-Axis Accelerometer: Measures linear acceleration and gravitational forces along the X, Y, and Z axes. It works by detecting changes in internal capacitance when a micro-machined mass shifts due to motion. It is ideal for determining static tilt angles relative to Earth’s gravity.
2. 3-Axis Gyroscope: Measures angular velocity (rotational speed) around the X, Y, and Z axes. Utilizing the Coriolis effect, it outputs values in degrees per second. It excels at capturing sudden, fast movements.
3. Digital Motion Processor (DMP): An onboard processor capable of offloading heavy mathematical computations from your main microcontroller. It can fuse raw data to directly calculate quaternions or Euler angles (roll, pitch, yaw).
4. Temperature Sensor: Built primarily to help calibrate sensor data drift caused by heat variations, but it can also be read directly to get environmental temperature.

Hardware Connection & Pinout (GY-521 Module)Most hobbyists use the sensor via the standard GY-521 breakout board. Connecting it to an Arduino, ESP32, or Raspberry Pi requires only 4 basic wires:
