MPU6050 3-axis Accelerometer Gyroscope Sensor
MPU6050 sensor module is complete 6-axis Motion Tracking Device. It combines 3-axis Gyroscope, 3-axis Accelerometer and Digital Motion Processor all in small package. Also, it has additional feature of on-chip Temperature sensor. It has I2C bus interface to communicate with the microcontrollers.
It has Auxiliary I2C bus to communicate with other sensor devices like 3-axis Magnetometer, Pressure sensor etc.
If 3-axis Magnetometer is connected to auxiliary I2C bus, then MPU6050 can provide complete 9-axis Motion Fusion output.
Let’s see MPU6050 inside sensors.
The MPU-6050 module has 8 pins,
INT:Â Interrupt digital output pin.
AD0:Â I2C Slave Address LSB pin. This is 0th bit in 7-bit slave address of device. If connected to VCC then it is read as logic one and slave address changes.
XCL:Â Auxiliary Serial Clock pin. This pin is used to connect other I2C interface enabled sensors SCL pin to MPU-6050.
XDA:Â Auxiliary Serial Data pin. This pin is used to connect other I2C interface enabled sensors SDA pin to MPU-6050.
SCL:Â Serial Clock pin. Connect this pin to microcontrollers SCL pin.
SDA:Â Serial Data pin. Connect this pin to microcontrollers SDA pin.
GND:Â Ground pin. Connect this pin to ground connection.
VCC:Â Power supply pin. Connect this pin to +5V DC supply.
MPU-6050 module has Slave address (When AD0 = 0, i.e. it is not connected to Vcc) as,
Slave Write address(SLA+W): 0xD0
Slave Read address(SLA+R): 0xD1
