At the beginning, the inertial measurement unit is an electronic device that measures and reports on a craft's velocity, orientation, and gravitational forces, using a combination of accelerometers,gyroscopes, and magnetometers. Now IMU sensor are commonly used in the Human-computer interaction(HCI), navigational purposes and balancing technology used in the Segway Personal Transporter as we all known.ط¢آ
The 10 DOF (degrees of the freedom) ط¢آ Mems IMU sensor is a compact and low cost IMU from DFRobot. It integrates the ADXL345 accelerometer, the HMC5883L magnetometer,the ITG-3205 gyro and the BMP280 barometricpressure sensor
. It's suitable for most of the controlling system because of the small dimension. The mounting holes make it possible to provide the highly accurate and stable sensor data.It embeds a low noise LDO regulator for supplying a wide range power input. Works with 3~8 volts power input. Certainly, the 10 DOF sensor is directly compatible with yourArduino boards
: V2.0 has upgraded the barometer sensor IC to BMP280.

The instrument not just can record steps (and calories) at real time, but show time. What is special is that the format of showing is pointer.
