Descriptions: GY521 GY 521 MPU-6050 MPU6050 MPU 6050 Sensor Module DC 3V 5V 3 Triple 3 Axis Analog Gyroscope Accelerometer Compatible Board For Arduino IIC I2C Interface Gyro Sensors

The MPU-6050 sensor module contains an accelerometer and a gyro in a single chip. It is very accurate, as it contains 16-bits analog to digital conversion hardware for each channel. Therefore it captures the x, y, and z channel at the same time. The sensor uses the I2C-bus to interface with the Arduino.

Measuring Temperature

The MPU-6050 can measure temperature over the range of -40 to 85°C.

The measurement is of the die itself and will typically be near ambient. This temperature can be used to offset the calibration of the accelerometer and gryo or can provide a general indication of the ambient temperature and temperature changes.

Accuracy is about ±1°C over the entire range.

Measuring Acceleration

The MPU-6050 can measure acceleration using its on-chip accelerometer with four programmable full scale ranges of ±2g, ±4g, ±8g and ±16g that can be set by the user.

The integrated 16-bit ADCs simultaneously sample the 3 axis of movement (X, Y, Z).

The X, Y and Z are relative to how the chip sits on the module as shown to the right and will ultimately be dependent on the orientation of the module in your project.

Initial calibration tolerance is ±3% with non-linearity typically 0.5%.

Measuring Rotation

The MPU-6050 can measure rotation using its on-chip gyroscope with four programmable full scale ranges of ±250°/s, ±500°/s, ±1000°/s and ±2000°/s that can be set by the user.

The integrated 16-bit ADCs simultaneously sample the 3 axis of rotation around the X, Y and Z axes. The sample rate can be adjusted from 3.9 to 8000 samples per second.

The axis of rotation are relative the the X, Y and Z shown to the right.

Digital Motion Processor (DMP)

The MPU-6050 has an embedded Digital Motion Processor that can be used to off-load computation of motion processing algorithms from the MCU, freeing it up to be doing other things.

It uses the data from the accelerometer, gyroscope and even external sensors such as magnetometers. It can process it at high speed and make it available to the host MCU.

Using the I2C Interface

The module uses the I2C interface for communications with the MCU. It supports two different I2C addresses; 0x68 and 0x69. That allows two devices to be used on the same bus or in case there is an address conflict with another device on the bus.

The ADO pin determines the I2C address to use. This pin has a built-in 4.7K pull-down resistor on the module. If the pin is left unconnected, the line will be pulled low and the default I2C address will be 0x68. To select 0x69, connect the ADO pin to 3.3V.

The SCL and SDA pins connect to the SCL and SDA pins on the MCU.
