3 Axis Accelerometer & Gyroscope MPU 6050

The MPU-6050 is a serious little piece of motion processing tech! By combining a MEMS 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an onboard Digital Motion Processor™ (DMP™) capable of processing complex 9-axis MotionFusion algorithms, the MPU-6050 does away with the cross-axis alignment problems that can creep up on discrete parts.

Use of Gyro in Smart Phone

This sensor’s function is to maintain and control the position, level or orientation based on the principle of angular momentum. When ‘Gyros’ used along with accelerometer senses motion from six axes i.e. right, left, up, down, forward and backward. It also detects the roll, pitch and yaw motions. Yaw, Roll and Pitch are the angular moments seen from three axes i.e. X, Y and Z. Using MEMS(Micro Electrical and Mechanical System) technology, (iPhone 4 uses this technology) gyroscopic sensors helps in navigation purpose and detecting the gesture recognition systems used in smartphones and tablets.

Gesture recognition user interfaces can support commands like a C motion to call up the camera (left), a unique gesture as a signature for authorization(right).
