GY-521 MPU-6050 Acceleration Sensor, 3 Axis Gyroscope and 3 Axis Accelerometer for ARDUINO

The GY-521 module is designed to determine the location and movement of an object in space using a 3-axis gyroscope and a 3-axis accelerometer. There is also a temperature sensor on board the module. This module can be used to design quadcopters, camera stabilizer or other projects made on the Arduino platform.

The gyroscope of the module measures the angular acceleration of the body along 3 axes (X, Y, Z), and the accelerometer calculates the acceleration of the body along one direction. To determine acceleration, the accelerometer uses the piezoelectric effect. At rest, the module constantly calibrates the sensor. Also, the sensor can determine and record dynamic parameters during movement.

The module board is designed on the basis of the MPU-6050 chip by the American company InvenSense, which consists of a digital processor for processing DMP (Digital Motion Processor) motion signals. With the help of the processor, the module itself can make calculations and process information from other external sensors. The chip data is contained in a FIFO ring buffer. The FIFO buffer storage size is 1024 bytes.

The module is connected to Arduino or other microprocessor devices using the I2C interface. I2C is connected via the SCL (clock) and SDA (sensor data) pins. The VCC and GND pins are used to power the board.

The voltage can be supplied from an external power supply or from the Arduino board. In addition, the GY-521 module includes a step-down linear regulator for 5V power supply. The LED located on the board lights up red when voltage is applied to it.

To work with the module in the Arduino IDE, the WIRE library is used. There is also an I2Cdevlib library for accessing the MPU-6050.
