Note: Battery and XBee transceivers are not included. They can be purchased separately at our store.
The Wireless MovSens 9DOF IMU - AHRS compatible incorporates three sensors - an ITG-3200 (triple-axis gyro), ADXL345 (triple-axis accelerometer), and HMC5883L (triple-axis magnetometer) - to give you nine degrees of inertial measurement. The outputs of all sensors are processed by an on-board ATmega328 and output over the air wirelessly using integrated XBee. With the work of Jordi Munoz and many others, the 9DOF IMU can become an Attitude and Heading Reference System (AHRS). This enables the 9DOF IMU to become a very powerful control mechanism for UAVs, autonomous vehicles and image stabilization systems.
The board comes programmed with the 8MHz Arduino bootloader and some example firmware that demos the outputs of all the sensors. Simply connect to the serial TX and RX pins with a 3.3V FTDI Basic Breakout, open a terminal program to 9600bps.
9 Degrees of Freedom on a single, flat board:
Outputs of all sensors processed by on-board ATmega328 and sent out via a serial stream & direct over-the-air wireless XBee transmission
Output pins match up with FTDI Basic Breakout, Bluetooth Mate, XBee Explorer
ON-OFF control switch and reset switch
Quick Start Guide
The MovSens wireless 9DOF IMU board is pre-loaded with a firmware that acquires accelerations, rotation rates and magnetic field strength along 3 axis's, and streams the data in real time. Following the steps below and you can have the first hand-on experience of how the wireless IMU board measures and transmits inertial signals remotely without wires.
Set up a pair of XBee modules for wireless data transmission. Set the baud rates for both XBee modules to 9600. You can buy the XBee Serial 1 module from Here, and buy the XBee Explorer Dongle from Here. If you need help in setting up XBee transceivers, please go to the XBee product page: Here;
Insert one XBee into Wireless MovSens 9DOF IMU board (please pay attention to the direction of XBee on board) and the other one into XBee Explorer Dongle.
Connect a Lithium Polymer Battery (Get it Here) to the IMU board, and insert the XBee Explorer Dongle to the USB port of your computer;
Turn on your wireless IMU board. At this point, the IMU board and the XBee Explorer Dongle form a point-to-point wireless sensor network. The data is transmitted wirelessly between them. Till now, your hardware is all set. Next, you will use Arduino or any serial terminal to view your data;
Open Arduino software and select the right port (Download from Here). Tip: To know which port your XBee is, you can unplug and plug the XBee Explorer Dongle and see which port number in the list disappears and reappears.
Click Tool >> Serial Monitor, the serial monitor window will pop up. Select the baud rate of 9600 at the bottom right of the Serial Monitor window, and you will see 9DOF data streaming out. That's your data!

I am a Biomedical Engineer. My interest is at the intersection of biomedical science and engineering technologies. Currently, my effort is focused on using latest IMU technologies to sense human body motion, and using this information to improve human health from biomedical side and improve user experience of engineering products.
