The MPU6050 contains both a 3-Axis Gyroscope and a 3-Axis accelerometer allowing measurements of both independentlybut all based around the same axesthus eliminating the problems of cross-axis errors when using separate devices.
Features:
Accelerometer ranges: ±2±4±8±16g
Gyroscope ranges: ± 25050010002000 °/s
Voltage range: 3.3V - 5V (the module include a low drop-out voltage regulator)
This simple module contains everything required to interface to the Arduino and other controllers via I2C (use the Wire Arduino library) and give motion sensing information for 3 axes - XY and Z.
