Me 3-Axis Accelerometer and Gyro Sensor
SKU: 11012 Weight: 20.00 Gram
Description:
Me 3-Axis Accelerometer and Gyro Sensor is a motion processing module. It can use to
measure the angular rate and the acceleration information of your robot or other
devices.
Me 3-Axis Accelerometer and Gyro Sensor is based on MPU-6050, it combines a 3-axis
gyroscope, 3-axis accelerometer, and a Digital Motion Processor™ (DMP) capable of
processing complex 9-axis Motion Fusion algorithms.
Features:
Tri-Axis angular rate sensor (gyro) with a sensitivity up to 131 LSBs/dps and a full-
scale range of ±250, ±500, ±1000, and ±2000dps
Tri-Axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and
±16g
Digital Motion Processing™ (DMP™) engine offloads complex MotionFusion,
sensor timing synchronization and gesture detection
Embedded algorithms for run-time bias and compass calibration. No user
intervention required
I2C Digital-output of 6 or 9-axis MotionFusion data in rotation matrix, quaternion,
Euler Angle, or raw data format
16mm interval M4 mounting holes, compatible with Makeblock beams
Easy wiring with 6 Pin RJ25 interface

Overview
The Me 3-Axis Accelerometer and Gyro Sensor is an ideal module for motion and posture detection
of robot. It includes a 3-axis accelerometer, a 3-axis angular velocity sensor, and a motion processor,
and provides I2C port for communication. It can be applied on the self-balancing cart, 4-axis aircraft,
robot, and mobile devices. It has the advantage of high-dynamic measurement range and low
current consumption. Its white ID means that it’s in I2C communication mode and should be
connected to the port with white ID on Makeblock Orion.

Pin definition
The port of Me 3-Axis Accelermeter and Gyro Sensor has 4 pins, and their functions are as follows:
Wiring mode
●
Connecting with Rj25
Since the port of Me 3-Axis Accelermeter and Gyro Sensor has white ID, you need to connect the
port with white ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example,
you can connect it to ports No. 3, 4, 6, 7, and 8 as follows:
●
Connecting with Dupont wire
When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its SCL and
SDA pins should be connected to I2C port, that is, the port A5 and A4 respectively as follows:

●
Arduino programming
If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to
control the Me 3-Axis Accelerometer and Gyro Sensor. This is a routine wrote in Arduino. When any
value is input through the serial monitor, the module receives it and returns the current value of X, Y,
and Z, so that we can identify the posture of current module. We can see the value of X, Y, and Z on
the serial monitor.
